Larian Studios Forums Baldur's Gate III Baldur's Gate III - Technical & Gameplay Problems Are rollbacks possible for Steam consumers?

KiraMira posted a link how you can retrieve old versions on Steam. I wouldn't call it "easy" though.

In the "Beta"s" option patch 6 is still visible in the dropdown, so you might try this one first. That's easy, jusyt select that branch and the game reinstalls itself.
