Lap 27 19:43:28 localhost.localdomain python[2501]: SELinux is preventing /bin/bash from getattr access on the chr_file /dev/pts/6.

If you believe that bash should be allowed getattr access on the 6 chr_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:
# grep bash /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Fix:

sudo systemctl stop docker.service
sudo dnf reinstall docker-selinux
sudo systemctl start docker.service
