This is exactly what has been happening to me for the past few days.

This is still occuring, I am on version v668 (0.668.0.6680659):
Things I observed:
- You can resize the windows.
- You cannot interact with any element within the windows.
- Studio tasks seem to run as the scheduler stats continue to update, and automatic saves are still performed.
- FPS stat doesn’t update.
- This issue occurs in every place, even the baseplate.
- There doesn’t seem to be any particular trigger other than stopping a play test.
- QT UI seems to continue to function, but viewport does not (might be related to the FPS freeze).
EDIT: Additional things I observed:
- Keyboard shortcuts continue to work
- Internet doesn’t seem to be accessible because automatic cloud saves do not occur
- The freeze seems to only affect Roblox GUI (e.g., non built-in plugins) but not QT
- This issue can occur regardless of the number of times you have play tested, even on the first play test.

Let’s reset here - there seem to be a few different issues. One is a crash after play solo is stopped (studio closes). Another is a soft lock/application not responding after play testing is stopped - possibly very quickly, though there have been reports that it happens anyways.
If you were getting the crash, please attempt to repro again - we believe this to be fixed due to some flag changes yesterday. (If Studio has been open a while, please close and restart before testing this).
For the softlock there hasn’t been a change rolled out yet.
In either cases, any time you do see this please submit a log (you can DM me). This helps us gather more info on the issue. This is for sure a timing thing, so some people may not see it at all, some may see it all the time. Knowing the frequency of the issue is also helpful. Thanks!

Thank you for the confirmation - anyone else that was getting the crash 100% (or frequently) is there a change in behavior?

Having a similar issue here. Playtesting a game in Studio causes it to crash in roughly up to 15 seconds. Tried playing regular games on PC and it also crashses in the same timeframe. Only started happening to me roughly 15 minutes ago.

Confirmed this. After maybe 10 seconds, when playtesting, it freezes and then crashes with no popup or anything.
To add on, this started happening to me like a few minutes ago.

The bug has not been solved for me at any time, in my case it has been like this since version 0.666 until now.

This bug makes development nearly impossible, I can’t work on anything without having studio soft-lock itself after bare minutes of terminating and re-opening the program. I have been using older version 0.664.0.6640713 for 4 days now, and haven’t experienced the issue so far, so if you are impacted by this, I recommend switching to the said version, I personally used Roblox Studio Mod Manager to install an older version. It’s just matter of time before Roblox automatically disables this version, so I hope engineers are working on a fix.

Thank you so much! I really needed to know how to switch versions.

Can confirm this bug is still present on 0.668.0.6680659.
It doesn’t happen to me every single time, I would say there’s about a 1/5 chance of it happening. No matter if I click Stop Playtest or Shift + F5, it soft locks and I am unable to interact with anything. I can press Ctrl + S, the window will pop up but does not let me do anything. Only way of closing the window is to end the task.

Occurs on 0.668.497.6681324 as well, extremely prevalent and occurs at random instances (around 90% of the time), I haven’t been able to determine any reasons it occurs (beta’s seem to have no effect and whether the larger stop in the home tab or the smaller one is pressed also seemingly has no effect) (playtest duration, actions and intensity also doesn’t seem to have any noticeable patterns on if studio freezes or not) but I should be able to provide logs if I’m told how to.
My freezing seems to be where you cannot interact with any studio elements (ui) but the Windows close button does work and studio can log / register actions, just not any mouse or keyboard inputs into it… (except alt + f4 that one worked)
Weirdly, some people experience crashes during playtesting after short periods, while I only experience it when specifically attempting to stop the playtest.

@permanent_fixture it seems this bug report is what you are looking for investigation on recent crashes.
This is not solved and should be looked into further.
