Zip file with backslash as path separator causes issues

[WEGFan]

If there's a zip file using \ in game's Mods folder, Loenn will have an issue loading it. After loading all files and enter the editor scene, the toolbars won't show up, and Loenn will crash with a bluescreen if you try to click something.

Sample zip file: BackslashTest.zip

Compress-Archive command in Windows PowerShell 5.1 can be used to create a zip file with \ as path separator, but PowerShell 7+ fixes this issue and used / instead.
