WRobot.exe does not open - no window, System.TypeLoadException at startup

Title: WRobot.exe does not open - no window, System.TypeLoadException at startup

Hi,

WRobot.exe does not open at all. No window appears, no error message is shown, and the process never stays in Task Manager. Windows only records the crash in Event Viewer.

SYSTEM

- Windows 10 Version 22H2 (fully updated with Windows Update, including KB5066791)

- .NET Framework 4.8.1 installed and repaired

- Visual C++ Redistributable 2015-2022, both x86 and x64, installed

- WRobot folder: C:\hobby\WRobot\WRobot (fresh download from the official site)

WHAT I ALREADY TRIED (none of this fixed it)

1. Run WRobot.exe as administrator

2. Unblocked the files (Properties > Unblock)

3. Checked the antivirus: Windows Security protection history is empty, nothing was blocked or quarantined

4. Repaired .NET Framework 4.8.1 and rebooted

5. Downloaded a fresh copy of WRobot and extracted it to a new folder

6. Installed Visual C++ Redistributables x86 and x64 and rebooted

7. Updated Windows with Windows Update

8. Ran Updater.exe: it opens and updates correctly

9. Renamed the Settings folder to Settings_old so WRobot creates a new one

The error is the same before and after all the steps above.

Could you tell me which type or assembly WRobot fails to load at startup, and what I can do to fix it? I can send screenshots or any extra logs you need.

Thanks!
