macOS 3.57.0 - can't find my designs after upgrade to BigSur

Hello Shapr3D Team,

I’m using the free version and had only 2 designs available. Yesterday I upgraded to Big Sur and it was fine at the beginning. But today for some reason I coudldn’t find my designs anymore. Instead it tries to start from scratch and allows be to create 2 new designs, like I never had ones before.

Please help. It’d be a pity to loose the work.
