Also I want you to send me crash report.

Which version of Forge and mod are you using?

crash-2020-01-29_19.08.22-client.txt

The crash log doesn't match the screen shot. The picture said a problem in ClientRegistory but the log said NPE in InGameScreen.

I rebuild with latest forge for Minecraft 1.15.1
