Sims 4 mods folders changing to read only

The sims 4 mods folders in Windows 11 are changing to read only and will not load into game due to this. I have run through an extensive list of corrections with help of AI, used command console to over ride this but it happens no matter what correction is made. The mods are enabled to load into game options, but mod window is grayed out and no mods appear in the list. I've tried test mods in a small batch (approx 10 mods of hair) that worked fine before May '26 update. I've tried loading the mods from a desktop folder and also tried to load the folder from C drive (after using a command console prompt provided by AI) deleted cache files and used a reconfig (provided by AI) in the mod text file. I've also checked Windows defender settings to make sure the folders are not protected through the controlled folder access setting (it's set to off), allowed through all firewalls, AV and disabled ransomeware (as instructed by AI) also changed accounts in PC and run launch via admin, and tried launching directly through .exe. None of this solutions worked. Prior to this, all game worked fine with mods before May 2026 update and all these mods were dl'ed within one month ago. Game does launch correctly without mods.
