I upgraded my project from 5.0 to 5.1 and tried to test it on my phone. Aside from performance, I had no problems with 5.0 but 5.1 makes the app stuck on a blank splash screen. This is the error I’m getting:

Note: I upgraded another project from 5.0 that worked, but it didn’t have UI or baked lighting.
