RMB rotation bringing up dropdown menu, Very annoying. UE5

So this is a problem that I’ve had since I started working with UE5. When I hold down RMB to rotate my scene or any other command for shifting perspective using RMB, upon release it opens up a dropdown menu which causes me to have to close it by clicking elsewhere on my scene and selecting another object every time I release RMB. It is super annoying and makes moving around my scene almost unbearable. I saw another post about this happening in ue4 but it was never resolved. I have tried reinstalling btw.

Hi, I’m having the same issue, and it’s really annoying
I hop that there will be answer for this problem soon
I’m new to UE, so I don’t know if there is an answer already, I find it strange that I didn’t find any solution to this question as I believe it should be annoyance to anyone using UE

Alas, you’re getting more functionality than I am. Holding down the RMB doesn’t do anything for me at all, but releasing it brings up the menu.
I’m very new to UE and cannot figure out how to rotate my view due to this.
Within the “editor preferences”, I am seeing the “panning mouse button” set to “right”. I tried setting it to “middle”, and this did not change the behavior of either mouse button.
I am using UE 5.3.2-29314046+++UE5+Release-5.3, in a perspective viewport. Although the other viewports have a similar issue.

EDIT: After creating a new project, I’m no longer seeing any of the issues. I didn’t save the old project and so am unable to compare the two.
