Mission Planner Simulation Failure?

I have been attempting to run a simple simulation in Mission Planner for the last couple of minutes. It appears to only happen on my computer, as my desktop can run the planned mission fine (I picked a random AMA airfield to run a simulation). Whenever I press “Arm” or “resume mission” this error message appears.

I’ve attempted to uninstall and reinstall Mission Planner multiple times. I’m about to go through and delete everything, including configuration files and drivers, just to be sure. Is there any way to stop this from happening?

The error was corrected after uninstalling ArduPilot, manually deleting all remaining Config files, deleting all drivers, and then reinstalling. I have no idea what happened but it’s working now lmao.
