This has been an issue for the last couple of years.
When I'm drawing with my Wacom Cintiq 22, holding spacebar and panning the canvas will sometimes break not only the pan function (you can no longer pan at all, not even clicking the scrollbars), it also breaks the Zoom function. You can not zoom in or out.
Minimizing the app will "return" the "zoom" function, however, the canvas in the middle of the screen disappears or doesn't actually move, regardless of the zoom% the UI is telling you it's at.
The only way to resolve is to restart the application. Then, it happens again intermittently using spacebar to pan the canvas, which is obviously an important function for illustration.
I've cancelled my subscription multiple times hoping this issue is fixed in each release, but it's still there. The only way I could fix the issue was to load a really old version of Photoshop, which I think was around 17-ish, but I noticed that that version is no longer available to install.
The software is virtually unusable until this issue is resolved.
Tested on Photoshop v22.0.1 AND Photoshop v23.4.1
Windows 11 -- Up-to-date (Before you say it's a Win11 issue, this was an issue before I upgraded as well.)
Intel i7-10700KF CPU @ 3.80GHz
Nvidia GeForce 2080 Super -- Drivers up-to-date
Wacom 22 (DTK-2260) -- Drivers up-to-date

Thank you for sharing @Dakota22179998ru3b. The team is wondering if you are able to rollback to Ps v20.0.10 20200706 r.120 does it solve this issue?
It may help if we could see your Photoshop System Info. Launch Photoshop, and select Help >System Info...and copy/paste the text in a reply.

To help us dig into this issue we need more > System Info.
1. In the System Info dialog, click Copy.
2. Attach or copy the info here to this thread or email daniel at adobe dot com.
We can learn a lot by understanding what is plugged into what monitor etc...
There have been specific Plug-ins that can create issues. Would like to make sure it's not something like this.
@CoryShubert I can not roll back to any version below v22.0 according to Creative Cloud.
Have not forgotten, everyone has unique hardware and determining what is slightly different is challenging.
Can one assume "the canvas in the middle of the screen disappears or doesn't actually move" is only on Cinitiq Monitor?
Maybe it is something we can learn from DXDiag... if you want to email me daniel at adobe dot com that output I can see if this is a bread crumb to this issue.
