Computer problem with Mission Planner

Does anybody have an idea what might be causing these errors? I’m sure it’s not Mission Planner but a problem with this computer. This computer was running Mission planner just fine but something changed and I’m not sure what. I have another computer on the same network that works fine.

Windows 11

Things I’ve tried:

  1. Re-installed Mission Planner several times.
  2. Deleted the config.xml file and had Mission Planner regenerate it.
  3. Reset Windows Firewall.
  4. Switched from Ethernet to WiFi and back.
