Mission Planner crashes when interacting with File Explorer (logs, params, etc.)

Hi everyone,
I’m running into a consistent crash issue with Mission Planner and hoping someone here might have insight or a workaround.

Issue description:
Mission Planner crashes whenever it tries to interact with the Windows File Explorer. This happens with any action that opens a file dialog, for example:

  • Loading log files

  • Comparing parameters

  • Opening/saving files through Mission Planner menus

As soon as the Windows file explorer dialog appears (or right after interacting with it), Mission Planner crashes.

What I’ve tried so far:

  • Restarting Mission Planner and the PC

  • Reinstalling Mission Planner

  • Running Mission Planner as Administrator

  • Running the standalone beta version

  • Testing with different Mission Planner versions

  • Updating Directx

The issue is fully reproducible and happens every time, which makes it impossible to work with logs or parameter files.

Environment :

  • Mission Planner version: 1.8 latest

  • Windows version: Windows 11 25H2

Has anyone encountered something similar?
