Unity version? Is this a bundle or assets file? Please check you're on latest nightly since it looks like the stack trace is off by a few lines.

[Kinetic1000]

1. 2020.3.18f1
2. bundle file
3. just redownloaded and the same issue still occurs

[nesrak1]

Can you paste an updated crash log?

It looks like it can't find a component attached to a GameObject. I'm guessing you modified a GameObject's components to point towards a non-existent asset which is the only way I can see this happening (components are always on the same file afaik so it can't be a dependency that needs to be loaded.) I've updated the code (redownload nightly) to hopefully show an error instead of crashing when no component is found.

yep that fixed it
