same =(

Same issue without the mod cupboard?

I'm trying to make my own modpack, but sometimes, in certain areas of the world, the game just says "server closed". Minecraft doesn't close, it just returns to the menu. When I tried to figure it out on my own and understand the logs, I didn't understand anything (English is not my native language, so it's difficult for me). I've been trying to solve the problem for the third month. So I ask if anyone is good at this and it's not difficult for you, to help me with this. If you need details, ask. I'll describe everything. What it looks like Logs

Hi i installed modpack to my server, it starts but when i join it crashes everytime, im running 1.20.1 forge version, all client mods are deleted from the server.   java.lang.NoClassDefFoundError:
