Ableton Forum

Hello everyone,
I rarely write on the forums, because I've never had problems with Ableton, but this time I really can't find a solution. The problem is more about a vst maybe, anyway I really hope you can help me.
When I press the space bar, or press the Stop button (the square between rec and play), the knob of the octave of the OSC 1 of this vst "DRC of Imaginando" is automatically lowered to the maximum.
There are neither automations nor midi learned/assigned nor key learned/assigned.
the project is new and clean.
I work on mac mini with m1 8gb 256gb
Does anyone know how to solve this problem?
Thanks to all for eventual indications

Guys I wanted to update you.
Nobody, not even the producers of the vst in question were able to help me,
Enough to want to reimburse me. This thing remains a mystery! I stay all nights to find a solution, but nothing!
I am very disappointed because I really wanted to use it ....
I tried uninstalling the vst, ableton, tried with ableton 11, unplugged the keyboard, sound card, hub and more. But nothing to do, I'm really going crazy...
If any of you should have any intuition about it even a small hypothesis ... I would be very grateful. Thank you!

Working fine here on windows 10 PC. DRC v2.7

hi mark Williams, thank you for your help!
yes I tried with my friend's pc and it works.
Also the manager of the vst company sent me a video that testified the correct functioning in ios.
I don't know if it was the latest model like mine, i use new mac mini with arm m1 processor, but I don't think that's the problem.
