After I ran fsck the Files app aka Nautilus in Ubuntu 22.04.3 LTS always takes approx. a minute to startup and then shows approx. 50-100 file icons/symbols in the left sidebar.
How can I get rid of them and what are they ? Please see attached image. I did not find an explanation for those icons on google. When I click on them, nothing happens. Many of those "directory names" start with square brackets.
The alternative file manager Krusader, on the other hand, works fine without problems.
Ubuntu is installed on a separate, bootable and persistent USB Harddrive.
As far as I remember, all began after I deleted some files on this USB Harddrive via access from Windows 10, which was booted from the main harddrive of my computer. Thereafter, Ubuntu did not boot, so I fixed it with fsck. After that, everything works fine again, with the exception of Finder getting slow and showing those symbols.
I tried to remove dead symbolic links with the terminal but got an error "too many levels of symbolic links".
lots of strange symbols in Ubuntu Files app
