So apparently on Macs the library folder is set to hidden by default. I tried what you were saying before, but thought it must not be creating the file because there are also other library folders on the Mac. Super confusing. But when I typed start-1.json into the finder it showed the location of the file and a greyed out library folder.

Silly Macs.

Thanks for your help, I just need to delete that file, but thought it wasn't creating it in the first place.

Spine was changing the colors of my imported art so I tried changing the color profile in Spine. After that I have not been able to open up Spine in the 4.0 verson. I can go back to 3.0 and it will open. I even reinstalled Spine and continued to have the same problem. When I open in 4.0 the screen is completely black. I tried deleting the file in library/application support, but it doesn't exist. Not sure what else to do at this point. I did go to the Mac console but and it looks like something is going on, but I'm not sure what. Attached should be what it showed in the console. Im on a Mac M1 Max with Ventura 13.4
