I believe this was already reported, but the fix seems to have only been added to 1.18, I also tried to use an older version just to see if that may help but the same crash happened when I tried to change a config, specifically, when I tried to select the World button.

Here's the crash report in case it's necessary.

Huh. I fixed the issue just never published the patch. Check CurseForge soon.
