I got the same problem but I fixed it by myself
Normally I use the mouse with my left hand so my primary button is the right one (when u have the mouse righthanded it’s usually the left one).
Since solo switching the windows options to the false (primary to left, secondary to right) and isn’t offering an option to change it, i simply fixed it with my Mousesoftware.
I created a Profil with switched prim/sec buttons and forcing the Profil to activate on solo start.
No problems anymore.
Maybe this could help anyone with the same problem
Thansk for sharing this, I am going to try that
