Critical issues with virtual drives with pCloud in Windows

Hi. I’m in the process o migration from Boxcryptor. Functionally I’m amazed by how better Cryptomator is and therefore I immediately purchased a paid licence and Android app.
But I’m facing some critical usability issues in Windows 11 with the virtual drives, both WinFSP (including local folder variant) and WebDAV. I’m trying to use it with pCloud. Symptoms are:

  1. WinSFP never allows me to create new file or delete one. I can only open, modify and save files. When I try to delete or copy file to virtual drive, Explorer hangs. This is not a problem with WebDav.
  2. Both WebDav and WinSFP vault can’t be normally locked, even with no open files. Even force killing Cryptomator doesn’t always work - it hangs until system restart. This makes WinFSP prety much unusable for me.
  3. Both WebDav and WinFSP tend to lose connection after some time with no way to recover but force killing Cryptomator - which doesn’t always work (see 2).
  4. These problems are not random but perfectly reproducible. I’ve encountered them on two Windows 11 machines.
    Edit: The problems seem to be limited to pCloud integration. Local folders mapped by either driver work fine.
