Ok... I think I figure it out what cause the crash.
IT WASN'T THE CHARACTER BUT IT WAS A SPECIFIC ITEM THAT IF I SELL, WILL CAUSE A SAVEGAME CRASH!
The item was this have one SKULL in my inventory.
Have no clue how Lariant going to find this and fix it.
I did have skulls in my inventory like you, threw them away following your message and it still crashed after I sold the rest to any npc and tried to save.
Tried also to go back with an older save. If it is related to a specific bugged object you get my rough guess is that it could be for sure something from the crypt.
I always start my games with clearing the crypt after I recruited all companions.
If I can't find a solution with my current save I might start a fresh game and go straight to the grove and ignore the crypt, see if that changes anything.
Plot thickens.
