The crash in the log is rather vague and does not imply Fusion (or any other specific mod) is responsible. What makes you suspect the crash is caused by Fusion?
Does the issue go away if you disable Fusion and keep everything else as is? If so, please narrow down what mod is needed besides Fusion to reproduce the crash.

yes it is

just fusion needed i guess. Also that crash sometimes doesn't come. I think it's a Neoforge issue.
