Massive X Crashing when tweaking any knobs in the wavetable section only

Avodroc42

Hello,

This is my first time using Massive X, I was able to reproduce these issues in Reaper as well as FL Studio, when I am using any knobs/ faders in this area:

I get an Error message like the crash log below.

Also of note when try and open the wavetable drop downs they are both empty.

Things I have tried to fix this:

1. Ran windows update
2. Reinstalled Massive X and MS VS C++ 2015-2022
3. Uninstalled and reinstalled Massive X, MS VS C++ 2015-2022 & 2013
4. Uninstalled MS virtual studio and massive X, and then let Native Access rebuild the needed Libraries, then reinstalled Massive X.

Still no love, any help would be , Massive 😉

An oddity from the FL Studio Plugin manager?

Happening to me too.

Crashed Live when changing OSC one.

Restarted, crashed again when changing OSC two.

Checked Native Access, no updates.

Both times, MX was wrapped in KK.
