Can confirm. I'm playing as a Bard and most (not all) Bard dialogue options bug out and leave me stuck in conversation. The work around I've found out is toggling the stuck character to engage in battle via the UI button. I then have them run out of range until the battle music ends.
A particularly weird one was using the Bard dialogue option on the boy in the water near the harpies. Post-battle Shadowheart and Astarion were stuck in dialogue and I couldn't get them out of it. I even killed them to see if that would fix them, but after I resurrected them they were still stuck in conversation. I had to go back to a save just before the harpy fight and try again. I avoided any Bard dialogue options and everything resolved without issue.
The other place I saw the Bard dialogue freeze the characters in conversation was the Bard dialogue with Volo in the goblin camp when he is singing on "stage".
I recommend reviewing those dialogues for sure, but also do another review of all bard dialogue options to see if the same issue is elsewhere.
