Arrow key press moves item diagonally, not to the side

Hey All, thank you for following up about this! 

After further investigation, accidental diagonal movement usually occurs when a "camera" layer is active in design tools (e.g., Adobe Animate). Is this the case for any of you?

If this is the case, can you please try the following?

• Disable Cameras/Overlays: Turn off active cameras or Prototype overlays.
• Check Plugins: If diagonal movement occurs, it may be caused by a "Move by Distance" plugin or similar tools.

After that, please try restarting Figma. Force-quit the desktop app or Figma in the browser to resolve the unexpected behavior. From there, please let us know if thing improve, or if you’re still running into issues. 

That said, if you’d prefer direct one on one support, you are still welcome to follow all the steps in this guide to submit a bug report.
