Lemmy 0.13.0 invalidated all authentication tokens meaning your current account will cause infinite spinners in lemmur. This has showed us that we should improve invalid auth handling, hence I have created a report for that: https://github.com/LemmurOrg/lemmur/issues/265
Do you see Internet Security Research Group under Settings > Security > Encryption & credentials > Trusted credentials in the System category?
If you do, do you see ISRC Root X1 or any other? If you don’t, are you able to import it manually?

It isn’t, and I can’t install it. The process seems to go okay using .pem file but there’s no sign of it afterwards in the list and Lemmr still doesn’t work.
