Encryption issue. Minecraft ForgeOptifine 1.20.1

Please help. We are creating a project in Minecraft and have encountered a problem when entering the local network: Encryption -> Disconnection. When I enter our world and open the port. I can enter, but my friend cannot. This happened after I updated my mod (adding new models) on MCreater and added it to the mods folder. When I deleted my mod created with MCreater, everything becomes fine, my friend was able to enter without problems and without any encryption or disconnections. What could be the problem? What do you advise to do? Please help
