After the release of the latest update, I saw many reports that the hands in the game stopped working. I spent several days trying to figure out this problem, since I was launching the game through Meta Quest and everything worked fine for me.
Today I launched the game through SteamVR and the same thing happened to me. It turned out that this issue occurs not only in my project but also in others. I came across numerous posts on Reddit and the Steam support forum. Valve simply broke something in the latest update, which came out on August 5.
So we’ll have to wait for them to fix it - there’s nothing I can do about it. If you want to fix the game for now, you just need to roll back to a previous version of SteamVR, or, for Oculus owners, simply use Meta Quest to launch it.
