Qt6Gui could not be found because dependency WrapOpenGL could not be found

[Driftwood]

I installed Qt just minutes ago, created a small app, and it won't run. Right out of the box, Qt is broken. I've made zero changes to anything, and it's broken. Here is the Message output in full:

I don't know how to fix this because I didn't do anything but install it. Again, I made no changes to Qt. These issues you see, they're right out-of-the-box . I'd like to get this straightened out, but I don't know how. Not sure why a fresh install would be broken in such a fashion as this.!

This is what I have installed:
