I have checked out the previous issues: https://jira.mongodb.org/browse/SERVER-50665 and https://jira.mongodb.org/browse/SERVER-48516
I have ensured a keyfile exists, and I then stopped and started the servers again (in the recommended order, first stop secondaries then master, etc.)
None of this helped and I have no idea what to do.
Mongo version 5.0.14
The `op` output for example:

Important to say: indexes did work before in my setup. Nothing changed, I just tried to create a few new indices and that happened.
