Nautilus search problems on Ubuntu 22.10 - Nautilus does not find files on one hard disk

Hallo Forum,
maybe anybody could give me a hint how to solve a strange nautilus error:

For some reasons I did a fresh install of Ubuntu 22.10. (was 22.10) on a M.2 harddisk.

The hard disk has seperate partitions for / and /home.

I did copy my old docs to /home (copy paste the documents without any system files)


Everything is working fine... However if search the hard disk for files it keeps searching forever without results.
With a one letter search I still get files. With 2 letters it starts searching without result. There are no errors.

The search works for other hard disks... If I use catfish I get results. Reinstalling nautilus does not help. I have the pdf- compress script add on in Nautilus.

Thanks for any tips to fix.
