solved Windows 11 Pro: XamlParseException on BigBox (Fresh Install)

[S and S]

Hello all. I'm starting to setup my retro box, but running into an issue with a fresh install of windows and a fresh install of launchbox. LaunchBox itself works fine, I'm able to use Keyboard and USB XBox Controller - it is when I open BigBox that I receive errors. I'll get the "bigbox" intro sound and nothing else... only way out is to Ctrl+Alt+Del

MiniPC: Beelink SER5 Plus AMD Mini PC, Ryzen 7 5800H (see Windows.png)

Quick details / things I've done thus far:

• Installed MAME 0.252 (merged)
• Deleted LaunchBox a few times and did another fresh install with the same result
• Updated Windows with Windows Updater
• Updated AMD Chipset to latest
• Installed License.yml for LaunchBox

Looking forward to any ideas! I look around at the forums and all I found was this topic here that wasn't responded to:

Errors point to there being an issue with the theme you're using. This error also happens a lot on drives that aren't NTFS formatted.

Using Default Theme (Default everything - clean & fresh install).

Checking drive format and placement here shortly. Support recommended no characters in my Windows username (which there is)

Interestingly enough, this issue was fixed by renaming my Window's user from "S&S" to "SandS"

Would this be considered a bug? I can imagine it's sort of common to have special characters in a directory on Windows.
