Ravewaker​  The thing about the read-only status is it doesn't always cause a problem by itself.  I've seen plenty of read-only folders be modified by games or other programs.  So while the behavior might be new, that doesn't mean it's definitely the cause of the problem.

I'm still running Windows 10, so my system isn't a valid comparison.  But I do know that Smart App Control and Windows Defender's Controlled Folder Access have both caused lots of problems recently.  And I also know that what you've described isn't a widespread issue, or there would be a LOT more players up in arms about their mods and custom content not loading.  So it has to be something on your end, at least in part, whether the problem is in fact the read-only status or something else.

You said you disabled Controlled Folder Access, but did you try a new Windows account and/or run the takeown command with CFA out of the way, so it couldn't reapply any settings?  And is Smart App Control running on your computer?

    Thank you for the follow-up.I understand you're suggesting it may be something on my end. However, this issue started immediately after the May 12, 2026 patch on a brand new Windows 11 PC where mods were working perfectly fine before the update. I have not made any major changes to my system.I have already:

    • Disabled Controlled Folder Access and Ransomware Protection
    • Taken full ownership of the folders
    • Used attrib commands
    • Moved the Mods folder to multiple locations (including C:)
    • Run the game as Administrator
    • Used a fresh .package file from popular creator (Trillyke)

    The Mods folder still reverts to read-only and the mod window remains completely grayed out/empty.If this is not yet a widespread issue, I’m happy to provide more information, but it does appear to be connected to the recent patch. Is there anything else on the development side that could be causing the game to stop reading .package files correctly?

    Thank you.
