Brush will switch to Eraser on it's own

[wakenthedead]

Lately this started happening, I don't know why, maybe because I updated PS?

I would be drawing and then I press 'E' to switch to Eraser and erase a line, then back to press 'B' for the drawing brush, and draw again, I will lift the pen from my wacom tablet after that line is drawn and it switches back to Eraser on it's own.
This makes it so when I'm working fast, I erase when I mean to draw and vice versa.
It doesn't happen all the time and it seems to happen more when I'm switching fast between eraser and brush and also when I change the eraser or brush size (with my custom shortcuts 'W' and 'Q', although I reckon it isn't because of the custom shortcuts as I had been using them before, forever, without any trouble.)
Any ideas? As this happened to anyone before?

Things I've tried for a fix and didn't work:
- Reset photoshop preferences
- Reset all brushes
- Uninstall/Reinstall Photoshop
- Reinstall wacom drivers
- Updating Windows and all other PC drivers
- Re-saving the brushes I'm using without the 'Include tool Settings'

Update:

Upon research, I found this is the problem: https://feedback.photoshop.com/photoshop_family/topics/turn-off-toggling-between-tools

Spring-Loaded Hotkeys.

Any advice on how to turn this bug feature off?

Update 2:

The main prob is that it recognizes my W and Q custom hotkeys for increasing and decreasing brush size to alternate between brush and eraser. So if I really want to make the brush go big or very small, I keep the key pressed and it happens, normally it wouldn't, I suppose it's picking up after the PS update. But yeah, the feature/bug exists

Update 3:

Found a solution, reverting back to an older version of Photoshop got rid of the issue, good job on yet another amazing update Adobe! /s

If your not already aware, photoshop 2020 has a new keyboard shortcut so one can use the Brush Tool as both a brush and eraser.

Paint and erase with the same brush

Use the ~ tilde key (below the escape or Esc key) to toggle between painting and erasing with the same brush tip.

Thanks for the info, however that's irrelevant to the topic.

This is good to know but the tilde is not involved in this bug. Using B and E to switch between brush and eraser will cause Photoshop to randomly switch tools....brush whilst erasing and vice versa. Unfortunately I don't see a suffiently old version to install from Creative Cloud to allow me to circumvent this bug. 

[Jeff Arola]

Well that means you don't need to use the Tool shortcuts that are causing the problem.

What version of photoshop did you go back to that doesn't have the issue?

[wakenthedead]

I'm using the very same shortcuts I had been using for years, 'W' and 'Q' to decrease and increase brush sizes, it has been working flawlessly, until the latest version of Photoshop was installed, and would then recognize both these custom keyboard shortcuts as a brush and would then do the tilde alternation between eraser and brush.

I had already explained this above though, hence why I said the explaining the feature was irrelevant, it isn't a feature problem, it's the new update that's recognizing the Increase/Decrease brush size tools as a brush, hence if you press these W or Q keys for too long, it'll alternate between eraser and brush, which is uncalled for, as all I want is to increase/decrease brush size for the brush that is selected, not change to eraser. Either way, it's working fine now that I reverted back to an older update. I reverted to the 20.0.9, which makes me think I shouldn't have bothered to update at all, besides not having this bug, it's also much faster on startup. Makes me wonder what kind of 'update' the following had been, since they were most definitely not performance ones.
Thanks though.

You can report the issue over here where adobe wants users to write up bugs.

This is happening to me to on my wacom 16 pro, I'll press B for brush and draw then move to E for eraser and periodically it will switch back to the previous tool drawing when im trying to erase or vise versa, I don't have any custom hotkeys and It happens whether windows ink is on or off and i've done the whole rodeo of Unistalling the program and drivers to no avail. I've found that pressing the hotkey for whatever tool im going to use twice will stop it from reverting as then the last tool was the same, It's extremely annoying to want to just erease small peice of something and have it malfunction back and forth, as mentioned by OP I didn't have this problem in CC2019, and It feels like bug that needs to get ironed out.

I have the same problem. i'm 2d artist and always use "e" and "b" buttons for brush and eraser. When i press "e" & "b" too fast -photoshop automatically switche it 1 in 10 times without my participation. Only one way to improve it - use older version of photoshop. It's very easy to find this bug - just draw smth for 2-3 min and always press "e" and "b" and u find that sometimes photoshop changed it
windows 10 10.0.18362 build 18362, wacom pro pth 660, photoshop v21.1.3 (still with this issue)

Change MODE at top left corner to Normal to revert to brush or to Clear becomes Eraser. Here is my link for more details:

Hi there,

Looks like I'm stuck with recent versions, presumably all with this same bug? Is there a way to get the latest version without this bug even if it's not shown in the Creative Cloud installer?

Oldest version I have is 21.2.4

Ideas? 

Thanks!

Trouble is now (12-30-2020) the oldest available version of Photoshop from Creative Cloud has this error. How difficult is this to fix? Photoshop isn't viable to me for 2D art with this issue.

Hello,

Just checking if any new solution has appeared since the last post? getting tired to always install older version of Adobe products because their updates always make things worse...(if you're frustrated by photoshop update bugs, pray you never have to update Premiere because then you'll enter the 9th circle of Hell)
