crashstack typically means corrupted file. A backup recovery may resolve this issue. Just note you will lose all progress up to the date of the recovery file.
btw- crashstack happens more often than we all want. Its ark.
yeah might have to put in a support ticket to see if anything can be done, but like I stated, its just when I or anyone else gets close to my base which would make me believe that crashstack would not matter as I would think that it would affect just joining as well anywhere on the map.
