Retrain Bug issue

Platform: PC

Do you have any mods? No

Please explain the issue is in as much detail as possible:
I went to go retrain my monk into a wizard and at around level four when you get to add your ability score point it bugs out and it won’t let me put in a point to anything and because if you leave it cancels the retraining process it’s unable to retrain my character

Yea, there’s a bug when respecing using NPC in tavern, since yesterdays patch. I tried it on companions and it bugs out. For me, I can’t even finish the very first level.
