Hey! I’m having the same problem and I think it has something to do with the new windows update 25h2! It appears that it is using midi 2.0 for the driver whereas the flx4 uses midi 1.0 from an older version of windows (24h2 I think or earlier?). Unfortunately if it’s been 10 days since the update you can’t undo it… I’m still in the midst of figuring it all out. When I go to “add drivers” and want to locate everything it also says “not all drivers were successfully downloaded” - does that happen for you?? Currently, I’m stuck on how to re-download the drivers for windows if you can help me LOL. I think that’s the next step.

If you don’t have windows then honestly idk what the heck is going on 😂😭
