Studio frequent crashes and freezes

I’m facing frequent crashes when dealing with Studio, mostly on a specific file. I believe these crashes/freezes have happened on other places as well, but I haven’t been able to record them. I’m not sure if a fix has been implemented as of posting this bug.

So far, I’ve been able to record the following cases:

  1. Crashes while loading a place:


    This has happened on the Blank Baseplate template once.

  2. Freezes after stopping a play test (most frequent):


    This occurred frequently back in March/early April as well, but it just recently came back. I’m aware of other threads covering this bug.

I’ve tried

  • Uninstalling + reinstalling Studio
  • Updating Studio
  • Disabling the Next Gen beta features
  • Clearing temp files

Hi,

Thank you for providing that place file! I’ve tried loading the place file locally a few times, and it seems to work fine for me. It might be helpful if you could find and upload a log corresponding to a crash incident.

Also do you have any beta feature enabled?

Thanks,

I was able to reproduce the freezing issue (June 3 @ 7:01pm). Here’s a recent log file, which I believe should correspond to one of the crashes/freezes.

And yes, a few beta features were enabled.

The place does not have any issues when I open and test it on a macOS system.

Hi,

I’ve tried loading this file multiple times on both Windows and Mac, and I haven’t encountered any crashes or hangs. I’ve also play-tested it several times, and it seems to work fine (with all beta features enabled or disabled).

Could you try to identify steps that consistently reproduce the issue (especially for the crash case)? Then we can test again to determine what’s really happening.

I also searched our internal database and found two crashes. One was due to an OOM (out-of-memory) issue, which we can’t do much about from our end. The other is related to an unrelated issue that some of our colleagues are already aware of and are working on a fix for.

Thanks

I haven’t been able to reproduce the crashing case, so I’m assuming it’s been fixed.
However, I was able to reproduce the freezing case (second one). From what I’ve observed, Studio often freezes after stopping any playtest (in Run mode) with this model in it:
train model.rbxm (11.7 KB)
Other unanchored models don’t have this issue from what I’ve tested, and the Acoustic Simulation feature is disabled.

Steps for reproduction:

  1. Open any place
  2. Insert the model
  3. Test it in Run mode
  4. Stop the test - freezes here (for me at least).

This problem seems to only be exclusive to the Run test mode. Testing it in Play mode and then stopping it doesn’t bring up any issues.

EDIT: the freezes are a little less frequent if I remove the LinearVelocity constraint.
