I have noticed that this bug is mainly a DD1 Bug where if you fight The thing from the Stars Solo it just removes the turn on the only char that in on the field locking you away from making any moves aside from the initial turn where you start.

the Main Problem here is that her Passives somehow lock the Battle indefenetly in an infinite 1HP vs 1HP loop of Scourge resisting deathsdoor and Thing having no more HP to summon more crystals and after waiting it is on the 30th cycle where the thing smacks Scourge and she resists death both at 1HP.

I don't know how this issue should be tackled at the moment, but I do think that people should know as her Arch Demon form should really be played Solo Party as she Blights the rest of the team in Arch form and at the moment I lost my save as I cannot exit or escape nor die in the endless battle.
