UE 4.26.2 crashes when opening project

[Maethor]

We have updated the unreal engine to 4.26.2, and updated the substance plugin from the Epic Games Store.

On UE 4.26.1 it seems to work fine.

Now the editor cannot open. It crashes when loading up, and it's not possible to revert to 4.26.1, nor 4.26.0.
Only way I can work on the project in general is to delete Substance and disable it.

I get the following for the crash report:
