Can't help you if you don't provide any information. Also, update to the latest version.

so no crash logs are generated as it happens strait on startup and i am using the latest ver of the mod 1.16.3-106 for 1.16.3 forge

What other mods are you using?

well need to apologize, i fixed the issue my self, so the curseforge app i use to play mc modded apparently keeps every mod file u update, so i had several dif ver of a bunch of mods and didnt realize until i started taking screen shots of the mod folder, so looks like its a bug on their part

No worries, glad you figured it out
