You can also use Larian's direct forms - arguably the surest way to ensure that someone sees your report. You can access their feedback form from the launcher, but accessing the bug reporting form is a little less clear. Use these two addresses:
https://larian.com/support/baldur-s-gate-3#support For feedback
https://larian.com/support/baldur-s-gate-3#modal For bug reporting
If you are ever reporting a bug on the forum, I'd highly recommend making sure you submit it through the bug reporting form as well, just to be sure.
