Consistent crashing on windows 10 when trying to import and replace another imported mesh, as well as when working with the glb format. Texture fails to upscale back to normal when selecting the export texture size and, say, choosing 512x512 before returning it back to 2k - the texture would remain blurry. 

Edit: Adding one star since it seems that the problems are mostly confined to the windows version. The linux has so far given me far less issues.

Edit edit: Dropping to 2 since the latest version on linux fails to import any file at all, blend obj fbx glb.
