Since the latest Update of Big Sur Beta Sweet Home 3D crashes on both my MacBook and on my iMac. I have tested both versions, 6.4.2 (from SourceForge) and 6.4.3 (just purchased from the App Store), both crash at startup, please see attached crashlog.

I was able to use Sweet Home 3D without issues since Beta 4 of Big Sur.

Any hints or workarounds? Uninstalling and reinstalling did not help.

Kind regards
Michael
