2 effects working, all others are not

I've enabled 5 effects in Muse Hub, but none of them are working when using Audacity. The only effects that do work are "Master" and "Pitch Shift", which are actually NOT loaded (they still say "GET" in the app).

I have tried uninstalling and reinstalling both Audacity (latest version), and Muse Hub (latest version) but still the same result.

I have also tried adding the vst's manually in Audacity (including the Master and Pitch Shift), and enabled all of them, yet I get the same results: The only two effects available remain Master and Pitch Shift.

Weirdly, the first time I downloaded Muse Hub, ALL effects were working. The issue started after I closed Audacity, and reopened again.

Any insight, anyone?
