MOGRT export impossible when user profile name contains special characters (WIN 11) - dialog boxes flash then close

Setup :

• Windows 11
• Local administrator account
• Account path has special character (C:\Users\François)
• Fresh AE 2026 install (same with fresh AE2025)

• Super basic test composition

The bug :

When exporting as MOGRT > dialogs flash > the export process fails silently before I get the “chose location” dialog. No error or crash.

Workaround : 

Create a new local account without special characters (c:\Users\temp\). Login to that account, open the same composition… exports just fine.
