HI, I can also confirm that the program works again

Hi, is there any progress at this issue? Would be great if this problem could be fixed.

Hi Emmanuel,

it did so and sent the bug Reports to Apple. But as I have written above its not the 3D mode that is not working, its the program that crashes at startup. So it might be a different reason.

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 ...
