Have you tried not using a third party client?

I mean using the official minecraft launcher. You are using a third party launcher, which in this case is multimc. Try without it [multimc]. If it still happens in the regular minecraft launcher, well then we know its not external interference.
Could you also provide the full crash log? It will look something like this.
(ignore the error details. just an example)
