Bug Memory Demons Leaking. Where is StackTrace?

After converting to ECS/Physics 1.0.0-prev-15 and clearing all errors I'm getting hard crashes every launch. Seems like memory leaks (getting warnings for memory leaks) but no stacktrace available. I did enable the debugging flags as instructed but can't find any detail on the trace. All I have is the editor log shows:

unity AA_EnableHighDpiScaling must be set before QCoreApplication is created

 

To clarify, I can launch fine. There are no errors in the console since I converted all scripts. When I play my scene, even if touching no input and taking no action, I get a crash in the worst case or warnings that allocations are being deleted because they are more than 4 frames old in the best case. It appears to be a memory leak but the output only points me to the collections package. I enabled JobTempMemoryLeakValidation but still no detail specific to my scripts.

Here is the first warning message contents:

Here's an example of the error I get if the Editor crashes:

@plu83 - Of note, when I relaunch the Editor, I do see this warning:

Couldn't parse HID descriptor with fast parser. Using fallback
UnityEngine.InputSystem.InputManager:OnNativeDeviceDiscovered (int,string)
UnityEngineInternal.Input.NativeInputSystem:NotifyDeviceDiscovered (int,string) (at /Users/bokken/build/output/unity/unity/Modules/Input/Private/Input.cs:129)

Nothing else at all.

 

I actually think the first error I shared was a red herring. The crash details above give a better representation of the problem. This is on MacOS Monterrey iMac (Retina 5K, 27-inch, Late 2015) Intel.

 

I just disabled all my custom systems and that cleared the mystery leak. I'll add them back one by one and trace it manually.

Just turned up in Unity 2023.1 and this is LITERALLY the only page on the internet that mentions these keywords. Is there any sort of workaround?

 

Also seeing this in Unity 2022.2.9f1. This occurs for me when stopping the game in editor.

 

I'm getting the exact same crash in 2022.2.9f1 on win10. Happens pretty frequently for me whilst the game is running and I'm making changes in the scene and inspector; will also happen occasionaly when stopping the game in editor. Any suggestions?

This solution worked for me
