What happened

After reformatting my PC, reinstalling updates and usual apps and so on, I moved my old installation of InvokeAI Community Edition 6.9, back to the same path, "E:\Invoke\6.9". I tried to execute it, and I got the error below.
After doing the usual trouble shooting of setting a different python on PATH, updated graphics driver and so on, I deleted the installation, and installed 6.9 again, and got the same error.

I also checked #8648, since it's the same error log, but mine is not directly under C:, but a custom path in a non-system drive.

I also tried a 5.12 installation. In this version, the launcher freezes for a while, before finally opening succesfuly.

Full error log below.

What you expected to happen

It should have launch both the 6.9 and 5.12 installations without an issue, it's the same path they each had last time. The relevant issue is with 6.9.

How to reproduce the problem

Start InvokeAI launcher
Select any 6.9 installation
Press "Launch"
Wait somewhere near 7 seconds.
