Crashing on startup in Windows 11

[brchristian]

I'm running a fresh install of Windows 11 on an Intel-based Mac using Parallels Desktop.

When I open Builder, I see:

UNHAPPY ERROR :(
you should save the BuilderX-lastcrash.log and post it at https://github.com/anotak/doombuilderx/issues/new.

So, here's the log:

Exception: Invalid URI: The Authority/Host could not be parsed.
Exception:    at System.Uri.CreateThis(String uri, Boolean dontEscape, UriKind uriKind)

Any ideas?
