Opening a Specific File Hangs Studio

[FriendlyBiscuit (Eric)]

I cannot work on a commissioned project since the latest studio update (version version-1eb2fdc84a3d4451). The file (which I cannot provide publicly but am willing to send to an employee) causes studio to hang/crash for multiple people. It happens 100% of the time when trying to open the file, and no crash log is saved. Studio just freezes and accepts no input.

Things I’ve tried:

• Waiting patiently (studio never recovered after 15 minutes of waiting)
• Having a friend who COULD somehow successfully open the file re-save it and send it to me (still crashed)
• Reset all studio settings to default
• Manually removed all installed and built-in studio plugins

The following output log is saved during each attempt to open said file:

When Studio hangs when opening game, could you please manually generate the full dump file and share with me? Please refer to below about how to generate full dump with windows task manager.

https://support.microsoft.com/en-us/help/931673/how-to-create-a-user-mode-process-dump-file-in-windows

The full dump file size may be very big (1G+), and the forum does not allow large file sharing. Please zip it, upload to google drive and share it with us.

Thanks a lot!

Best Regards,

Will do. Once I get back to my house after running some errands I’ll take care of it.

Thanks for your sharing. So far, I have received dump files from two developers, which seem to be the same issue. Studio seems to have some deadlock issue.

Will file an ticket for this, and will work on it:-) Thanks a lot for your sharing.

Btw, I just by accident clicked the “Flag” button in your post:-)

[FriendlyBiscuit (Eric)]

Possible ETA on looking into and/or fixing the issue?

[lll_xyz]

We may find the reason for the freeze. Before the fix, maybe you can try to temporarily change the FFlag as below:

1: under the Studio installation folder (where the RobloxStudioBeta.exe locates), create a subfolder “ClientSettings”
2: Under the ClientSettings folder, create a file: “ClientAppSettings.json”, with below content
{
“FIntHttpClientHandlerFixed”:10
}
If number 10 not helps, try it 20
Please let me know if it helps:-) Thanks a lot!

[FriendlyBiscuit (Eric)]

The temporary solution (provided in DM by @lll_xyz) was to set FFlagAddPackageService to false in ClientAppSettings.json. This allowed my file to load successfully. Thanks a bunch!!

Just wanted to add that I also have this issue on the select few places where I have packages, though not with any that don’t have packages.
