Further report:
1. The above issue was immediately resolved after I removed the RimTalk mod.
2. No errors were reported in the logs when the problem occurred.

After I moved RimTalk to the very end of the mod sorting list, I was able to successfully click on the options.
Although the visual effects of highlighting and graying out were still present, this time I could interact successfully, so my problem was kind of solved.

Glad it got resolved! Thanks for reporting this

Could you please make it compatible with frameworks for race mods, such as AncOT Library, so that errors like this log do not occur due to frameworks for race mods?

@prebator Thanks for reporting. I couldn’t reproduce the issue with the race mod + Ancot Library. Are you using any weapon mods that rely on Ancot? If so, please check which exact mod is causing the problem and let me know. I need that to reproduce and fix it.
