Getting error code on mac O52V:SELK:SELK

After selecting existing vault file, getting this error. Note that I use it on Windows and another Mac just fine.

Cryptomator 1.7.5, OneDrive, Fuse-T, Catalina 10.15.7

But trying to set up on new Mac for first time, it gives me this error:

Cryptomator does not recognise this folder as a vault.
The reason could be an incomplete sync of the vault file and thus some important files not available local.
