I've had this with a few aircraft now. Basically, the aircraft starts shaking once you speed up a bit and it somehow accelerates itself without even having any engines. I found that it it's slightly better when I increase the wing thiccness but it still happens and I never had this problem before.
Like, I always have my aircraft's wings at 10% thickness just because I build over them with fuselages. But I get this issue pretty much always now when I do that.
Started happening after the last update. Please see the video for more info:

Anybody knows how to get rid of this problem?
I've tried increasing wing mass, reducing drag, making the wing of smaller individual wings and re-attaching the wings with shift+K but still no luck. Someone else has been able to replicate the issue as well so it's also not my build. Just to be sure I did try reinstalling and removing all mods but also no luck.
