hey guys, if you're looking for a mod to fix this issue then you can use this one. I've lightly tested it and it fixes both the Not able to convince lords infinite loop and the encyclopedia name clicking sending you to your own character entry instead of the lord you're attempting to look at.
Fixes the bugged blank conversation screen when persuading lord to join player kingdom.

Simply replace your DLL located in C:\Program Files (x86)\Steam\steamapps\common\Mount & Blade II Bannerlord\bin\Win64_Shipping_Client with the one from the mod and you are all set.
I'm honestly so happy about this, I can finally move forward with the game in this new branch as my own ruler without having to be my own entire army. Big props to MortalDVall for the mod
