To be fair to Bk, Boba is a lot heavier now, and it must have been off putting seeing him in his pants.Black Krrsantan is physically bigger than Chewbacca. Krrsantan is centuries old, a former gladiator and supposedly a skilled bounty hunter.
Chewie ripped arms out of sockets, but Krrsantan just throws Boba around a bit and then gives him a hug.
Why didn’t Krrsantan have the big gun we first see him with and just shoot Boba whilst he was incapacitated? It’s all just too boring and contrived.
