So what is probably happening is that while you may have Windows Defender disabled now, it has still previously blocked the app. So what I want you to try is to add a few exclusions in the Windows Defender Virus and threat protection page, and one more step after once you've done that.
Add a folder exclusion for
\Documents\Larian StudiosAdd a process exclusion for
LariLauncherAdd a process exclusion for
bg3.exeAdd a process exclusion for
bg3_dx11.exeThen navigate these course of actions
Virus and threat protection > settings > Manage settings > Manage Controlled folder access > Allow an app through controlled folder access > Allow app
When you're there, which should look something like the picture below, make sure bg3.exe and bg3_dx11.exe isn't blocked already in that list.

I've had remote desktop sessions with interested community members tonight and have personally tested and verified this for an identical issue, so it should hopefully be identical enough to solve it for you!
