SELinux is preventing blocking-1 from 'write' accesses 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.
Do
allow this access for now by executing:
# ausearch -c 'blocking-1' --raw | audit2allow -M my-blocking1
# semodule -X 300 -i my-blocking1.pp
