Windows 11 Smart App Control (SAC) blocks XMPlay plugins/DLLs

I wanted to share a quick heads-up regarding a recent issue on Windows 11 that might affect other users.
Recently, Windows 11's Smart App Control (SAC) started aggressively blocking several of my XMPlay input plugins.

Because these hobbyist DLLs are unsigned and have a low global prevalence in Microsoft's cloud database, the AI-driven security algorithm flags them as a threat and blocks them from loading entirely.

The only immediate fix on the user end was to completely disable Smart App Control in Windows settings.

I'm posting this here for two reasons:

To let other users know what's happening if their plugins suddenly stop working or disappear.

To ask developers if there is any way to compile future DLLs to be more "SAC-friendly" (e.g., avoiding UPX packers or aggressive code compression that often triggers false positives), as getting expensive EV certificates for free plugins is obviously out of the question.

Keep up the amazing work, I absolutely love XMPlay!
