Note that Larian essentially takes full ownership of anything you upload on their own mod Loader and that you can still install external mods despite claims from some players that you can't.
I've seen some wild discourse on the Steam forums in recent days so let me remind you: It will take some time for some mods to be updated so stay patient.
You may also run into issues with the update itself even if you never used mods. Larian is aware and recommends a full re-download and installation which of course can be very frustrating. Maybe it's worth waiting a couple weeks or months before jumping back into the game.
