PowerToys: Error trying to open FancyZones editor
ℹ Computer information
- PowerToys version: 0.25.0
- PowerToy Utility: FancyZones
- Running PowerToys as Admin: Yes
- Windows build number: 19041.610 (Note: updated to 19042.630, still getting the same result)
📝 Provide detailed reproduction steps (if any)
- Make sure PowerToys is open, then either: 2a. Press the shortcut to open the FancyZones editor OR 2b. Click the FancyZones editor button in the PowerToys UI
Potentially important note: I just purchased an LG 34GP83A-B ultrawide monitor, and this only started after I set it up with my PC.
✔️ Expected result
The FancyZones editor opens
❌ Actual result
I get an error message:
Error parsing device info data.: Could not load file or assembly 'System.Numerics.Vectors, Version=4.1.3.0, Culture=neutral, PublicKeyToken=b03f7f11d50a3a' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
