1.20.1 Please offer help on this. "Exception in server tick loop" (1.20.1 - 47.2.17)

[wkqi]

Hello all, 
I have had this crash ("Exception in server tick loop") many times on my self-made modpack. Due to my lack of knowledge, I can't figure out how to solve this issue alone. 
My pack is on Forge 1.20.1  -  47.2.17

Edit:  I can successfully launch the game, but it crashes in singleplayer. I haven't tried playing multiplayer yet. 

Please offer help!! Thank you!! orzz
