Crashing on startup when adding the lastest version of 1.16.5 modernfix (1.13.0)

https://gist.github.com/LegendaryCrystalFox/add0afb171496e8bf5ae119bb1b31838

Try without OptiFine installed. If that works, add mixin.bugfix.preserve_early_window_pos=false to config/modernfix-mixins.properties and see if that fixes it.

I tired without OptiFine and it works but adding it back in and doing the config thing it doesnt work

Never mind I seem to have not done the config thing correctly I believe it is working now

This will be fixed properly in the next release, but please note I cannot provide any guarantee of support for issues encountered while OptiFine is used.

Alright, thanks for your help!
