After updating to 24.3, all settings, actions, tools, workspaces, etc is gone

The same thing just happened to me. All setting gone, all brushes gone, 0 signs of previous photoshop version. I don't have auto-updates on I always check migrate settings. Am I cooked now? I can't even imagine how to recover from this... I need to do my work with my brushes which I was creating and collecting for last 8 years.

You need to make it a habit to always save out actions and brushes. Until you do that, they are just temporarily stored in your preferences, and will disappear if preferences are reset.

Each PS version has its own preferences folder in your user account. In other words, it's all version specific. That's the way it has to be, since new code means that settings may not have exactly the same meaning in the new version, or they may not apply at all.

This is nothing new, this is how Photoshop has always worked, right from the beginning.

Preferences can get reset spontaneously. It's not something that happens under normal circumstances, but Photoshop rewrites your preferences in their entirety on every application shutdown. An irregular shutdown can prevent that, as can an issue with your user account permissions.

Yeah, this just happened to me. I did not update my PS.. I do not have auto update on either. Yet I log in today and all of previous brushes and most importantly actions are gone. They previous PS doesnt exist on my Mac anymore. ts like they came and snatched all my stuff =( This is my busy season and I did not plan on creating all new actions from scratch. I dont even remember how I did each and every one. ADOBE COUNT YOUR DAYS! 

@zarcosp12670394 Please read this page on how to migrate your items.

The only way they would be missing from a previous version is if you did not save them before a reset.

Until they are saved, presets including actions, brushes, etc. are temporary items.

Hello thanks for your tip but there is nothing to migrate everything is vanish from previous version..Actions, brushes, all gone. 
Instead getting hit every day with the comercials why dont Adobe Mickey Mouse engineers spend their time fixing the problems highlighted by the Adobe comunity? Shame on you Adobe 

You probably have an old/underpowered GPU. That's the critical component nowadays, and where newer versions tighten the requirements.

I know of exactly one bug in Photoshop 25.0  (missing adjustment icons). And that's after 8-hours-a-day professional heavy duty use.

Hope you can recover your preveous versions.

PS 2024 is so full of bugs that I don't use it.

Are the engineers are so crazy for AI that they threw out what worked before?

The same issue happened to me. I always migrate from previous version. I have that option selected with auto update on. However, this time everything was deleted. The folder containing the settings from the previous version has been deleted. The presets can be recreated and the brushes, patterns, etc can be manually migrated but it's infuriating and a huge suck on productivity. There are many threads complaing about this and generally the responses are not helpful or sassy. I guess I will try saving the preset file in a different location. Trial # 4,596. 

I'm guessing you already did but check for any resources in C:\Users\[user name]\AppData\Roaming\Adobe\Adobe Photoshop [version]\Presets\

To be more accurate, the folder is basically not there:
It was supposed to be 2022 version in there, but it's gone. Everything connected to the previous version is just gone from my drives.
