P: Dialog boxes / error messages pop up invisibly - macOS

I was able to fix this by right clicking on myPS icon in the dock and selecting "none" from the options menu. It appears that photoshop is moving the dialogs to the desktop where it was opened originally instead of where it is now. May not fix everyone's situation but it worked for me. hope it helps.

One would think that it's just a multi-screen issue, however I have this problem daily and I've only ever had one monitor connected to my Mac Pro (2019).  It's something else. I have Ventura, and I'm not sure whether the issue started before I upgraded or not.  Very frustrating, as some days I can't use Photoshop at all.  We pay too much for this software for disabling bugs like this.

I think this is related to multiple screens and maybe even changing which screen is the main screen.

After much frustration with this bug, I have discovered that the Beta version of PS is not exhibiting this issue.

Just filmed a video cuz of course that error again...But I can't send you the video as I can only send you a link and I don't have time to figure out how to make that link. Busy time with work and PS is slowing me down. But pretty much what MarkDS said: nothing really to see. Photoshop open with the file, you do something which triggers a popup window...and nothing...nothing to see...just "bing-bing-bing!" sound that the file is unaccesible (due to the popup window that is not there). The only thing to see is my hand clicking on the option button and double-click on the PS icon which makes the popup window appear. It's a good workaround, and in all honesty that error wouldn't be a big deal if it happens once in a while. But pretty much every popup window hidden, is frustrating and add extra time to my workflow, and at this time of year I can't afford this. I'll probably downgrade again to 24.0. That version was decent. had the error only once in a while. The only thing keeping me now with the new PS is the Remove tool. And it's frustrating. One of the selling points of the Adobe subscription are the updates. Well I can't really update.

And sorry but I don't have time to do a whole bunch of back and forth with tech support.

Cory, the problem is that there is nothing to see. For example, it has happened to me that if I tried to save a PSD file which exceeds the size limits of PSD, a dialog is supposed to pop-up in front of the workspace that says the file is too big and asks whether one wantsa to save as PSB; however that dialog remains hidden even though it is active, so the whole application is stuck waiting for an answer that can't be given because there is nothing visible to answer to. The only solution I foun d was to Force Quit Photoshop, upon which one sees that Dialog for a brief second or so before all shuts down, releasing the application to be re-opened and reused. I am on Mac OS Monterey. I could actually not care whse defective script caused this, because I'll never know. What I do know is that once there is clear evidencve from so many people of this being a problem with an Adobe application, it is Adobe's responsibility to get to the bottom of it, perhaps involving collaboration with Apple, depending on what the analysis of basic cause shows.

@teodorac48712377 would it be posible for you to share a video of your workspace so the team can see what you are seeing?

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.  

There has got to be more to the story than just a widespread Photoshop bug. It has to be related to the OS somehow. I contributed to this thread many months ago, experiencing the same problem. Through whatever various combination of software updates (from Adobe, Apple, Wacom, etc.) I haven't seen this issue in a LONG time. Some people have it on Ventura, some on Monterey... there doesn't seem to be a rhyme or reason, which is probably why it's still issue. 

Is there some other commonality we're missing? Wacom tablets? Using your Mac with an external monitor versus a laptop screen? Has to be something. 

Just updated to Ps 24.5 a few days ago and the invisible window thing happens now ALL THE TIME. (I was on 24.0 before, for months, downgraded to that version after an update that was giving me that error all the time. I decided to take a leap of faith and update now, because I was tired of going back and forth with Beta just to use the Remove tool...)

Any window like "You sure you want to do that? (delete that, close the file whatever) - hidden. Lots of settings windows are hidden too. It's been 30 min I've been retouching this morning and I had the invisible window thing 5 times already!!! Many many many thanks to the guy who posted the option-click-on-Ps-icon trick, as Ps would be absolutely unusable without that. I'm on Monterrey 12.4.
