Steps to reproduce

I was making the game stop-resume while using the profiler in Godot, at this time it gave such an error.

Minimal reproduction project (MRP)

I dont think i need to upload my project here for this bug.

Please add this code to a new empty project and see if the error still occurs, if it does please upload that project as an MRP, if it doesn't then this needs more details and steps and it'll be very hard to identify what's wrong with so limited information

A small Godot project which reproduces the issue, with no unnecessary files included. Be sure to not include the .godot folder in the archive (but keep project.godot).
Having an MRP is very important for contributors to be able to reproduce the bug in the same way that you are experiencing it. When testing a potential fix for the issue, contributors will use the MRP to validate that the fix is working as intended.
Drag and drop a ZIP archive to upload it (max 10 MB). Do not select another field until the project is done uploading.
Note for C# users: If your issue is not C#-specific, please upload a minimal reproduction project written in GDScript. This will make it easier for contributors to reproduce the issue locally as not everyone has a .NET setup available.

Although the error code runs continuously during the game, it only appeared once when stopping and restarting the game while using the profiler. I think the problem may have occurred because I stopped the game during the timeout line.

That sounds very likely, some form of memory or reference issue

Though you are doing some pretty risky code by entering an infinite recursion by calling _random -> _random_finished -> _random, that seems like a thing you shouldn't be doing

Closing as no MRP has been uploaded, if one is this can be reopened
