Issues with Unity 2019.3.xf1

Hello,

For the last 2 days I have been using Unity 2019.3.7f1 and have been getting SPAMMED by the console with the following error:

TLS Allocator ALLOC_TEMP_THREAD, underlying allocator ALLOC_TEMP_THREAD has unfreed allocations, size 8901

as well as

I upgraded to unity 2019.3.8f1 and that did not resolve the issue. I created an entirely new project and part of the way of importing assets unity crashed (it crashed a lot before) and started getting the errors aswell. It will max out the 999+ errors in all 3 types in about 5-10 seconds. This happens in blank scenes, scenes with objects, in admin mode, new projects, old projects that have been upgraded, etc. But the errors don’t start happening until I begin importing assets. The first few times I thought it may have been one specific asset causing the issues but after multiple tries it seems totally random. 2019.3 appears to be broken and unusable at this time which is very unfortunate. Any ideas?

The following things did not work:

  • Clearing GI cache
  • Restarting Unity
  • Deleting assets that have been installed
  • Using HDRP or URP
  • Creating a new scene/blank scene
  • Reimporting all in Assets menu

Update: Seems unity 2019.3 crashes randomly while using it and when I relaunch the errors get quicker. Now generates 20,000+ in a few minutes. I am on my 3rd project reimport less and less assets each time to try to narrow it down but even on totally blank scenes it still happens.

Ryzen 9 3900x
GTX 1070Ti
32GB DDR4 3600Mhz ram
650 watt PSU

Any ideas?

Anyone from Unity care to respond to this please ? Upgrading to 2019.3.x completely f–up my projects. Can we please get a status update on this ? Error after error. Its extremely frustrating.
