Ah, it’s bbpress – normally a good choice. I’ve installed it on one of my sites to test, and some settings you may want to try: Settings, Forums.

The only thing in its settings that might be worth changing is to toggle Fancy editor

If not, try disabling other plugins one at a time to see if they fix it.  Especially any editing plugins you may have.

Then change to a different theme.

It can take a fair bit of time and faff to sort, unfortunately. 🙁
