Narrowed it down to this mod, the prisoner tab on prisoners is just has a vague line and screen flashes and it returns a null reference error.
Ran it with royalty, ideology, harmony, hugslib(still errored without it but makes log exporting easier), modmanager, prison labour.
Link to log idk if it helps at all, https://gist.github.com/HugsLibRecordKeeper/4e92f50c5686774f1a69a4eed164b0af

Just tried to unsub and resub, didn't help.
