After making a change in omnibar and opening your options again it crashes the game.

Ye i have the same problem. Extremely annoying

experienced same thing, actually i never had any issues with the "stock" settings but once i enabled more spells - i started getting this issue.

Same here for me and my friend, we cant even play with it, please solve this soon!!

This is still an issue. It won't crash the game for me but freeze for about 10 to 20 seconds. Doing anything in the OmniBar settings and clicking another tab (or accessing any other setting as in closing the settings and opening them again) causes this issue.
9:40 in this video shows the exact issue I am having: https://youtu.be/mAZTbVjmQQo?si=W4RHdu9juL8agzhq&t=580

Same problem, Game stops responding after going to omnibar options and switching to another addons options.
