You can find Larian's official bug report form here:

https://larian.com/support/baldur-s-gate-3?ver=4.1.101.4425#modal

If you just want to offer feedback on something that isn't a formal bug report, you can also use:

https://larian.com/support/baldur-s-gate-3?ver=4.1.101.4425#feedback

The first one is more specifically for actual bugs, and will usually garner an acknowledgement from the team, while the second one tends to only receive automated responses.
