Files doesnt load/appear/visible in nextcloud client

The Nextcloud client connects successfully and I can log in, but no files are visible.
I have tried running files:scan --all and occ maintenance:mimetype:update-js and some other commands.
No matter what I tried, the files do not load in the mobile or desktop app.
Everything was working fine until I upgraded to version 31.
Can you help me please?

Thank you very much
