Vst plugins scan failed

I have a month using mpc beats as daw, my plugins two days ago worked fine, but now they stopped loading, I did not make any configuration changes, I tried using the same plugins in the same folder in reaper, everything works fine in reaper, but I want keep using mpc beats, any advice or suggestions to solve this.

If they worked two days ago, and now they don't. Something changed.

Also.....

Have you tried re-scanning your plugin folder? Or adding the VST to a new project to see if it has something to do with your existing project?
