Description of problem: SELinux is preventing blocking-2 from 'connectto' accesses on the unix_stream_socket /run/systemd/userdb/io.systemd.DynamicUser. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that blocking-2 should be allowed connectto access on the io.systemd.DynamicUser unix_stream_socket by default. Then you should report this as a bug. You can generate a local policy module to allow this access.

I have the same error but with blocking-1: SELinux is preventing blocking-1 from write access on the sock_file io.systemd.DynamicUser. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that blocking-1 should be allowed write access on the io.systemd.DynamicUser sock_file by default. Then you should report this as a bug. You can generate a local policy module to allow this access.

Then opening the directory in Thunar (Xfce). PS: I'm almost sure I already commented on this issue. There may be a duplicate but it's impossible to find anything on this bug tracker.
It may be a different issue, just noticed the difference: connectto vs write
I got those errors after upgrade to Fedora 43
I think that this was my issue https://bugzilla.redhat.com/show_bug.cgi?id=2408906 Sorry for the noise.
