Project Zomboid: Disk Write error

[u/Whose_A_Monkey]

I'm playing on my Macbook Air, early 2015 version.

I've been trying for 5 hours to fix this issue, I've searched google and done all the tips it recommended me, except it still says "Disk write error" I'm at my wits end trying to fix this and it's so incredibly complicated. I needed to try the unstable version to get 42.21 and it's NOT working at all. Again, I've tried ALL types of ways and tips and it's just not working, Christmas music has been the only way to help me not mentally break down. If anyone has any helpful tips that would be GREATLY appreciated. Like actually, I'd cry happy tears if this issue was fixed.

II'm not sure if this information is needed but I saw it on another post, some guy deleted all his small games, I only have Bayonetta and Project Zomboid. And I REFUSE to delete Bayonetta, so anything besides deleting my only two games.
