Xcode 11 Can't Open Project/ Crashes

I downloaded xcode 11 today because my phone somehow downloaded iOS13 and I needed to upgrade to hook it up. Unfortunately, now when I try to open xcode on this project it crashes.

I feel like I have tried everything I have read- delete derived data, delete xcode and redownload (have even tried again with 10 and it won't open), delete xcshareddata, also tried turning off icloud.

No idea what else to try
