Game Build instantly getting stack overflow on first scene [Fixed]

Using unity 2019.4.13f1 Every time I try to build my game I get this stack overflow error and then the building scene bar just gets stuck and never loads no matter how long I wait. My attempted fixes *Re-imported all assets *Tested an empty scene and it still does the same thing. *Optimize mesh data is turned off. *tried building to different locations.

No other errors pop up and the error i get just is no help at all..

Created a second copy of the game to do some testing. *deleting all code and then building again works which isn't a good sign in terms of how easy this will be to figure out.
I tried deleting everything in resources which tells me it may be related.
