Editing 360 Videos without Adobe Premiere Pro

Long story short, I have a scratch on the 360 mod lens. It happens to be on the forward facing camera (or "initial view camera"). Insta360 wants $200 + shipping to repair my 360 lens and I really don't want to spend that. Thus, when I shoot video with the 360 lens, I use my rear facing camera as the primary lens and then using Insta360 Studio desktop I insert keyframes to rotate the view. This works fine if, I'm going to export the video in Free Capture mode (non-360 video).

However, I want to edit and publish some 360 videos as well. Unfortunately, Insta360 Studio desktop has a bug. If I rotate the field of view of a 360 video to show my rear facing camera, then lock the view, then export the 360 video, the software does not preserve the locked view. Thus, all my 360 videos have the initial view of the lens with the scratch.

All I need to do is rotate the intial view 180 degrees on each 360 video I want to publish. Obviously, I know that I can edit 360 videos in Adobe Premiere Pro with the GoPro Reframe Plugin. However, my Macbook Pro is a 2015 model and I'm unable to rotate the view because it tells me that my video card won't allow hardware accelleration (my laptop is too old). So, I'm stuck. Insta360 Studio has a bug that they won't fix, and my laptop can't do this simple edit with Adobe Premier Pro.

I see there are a couple of other video editing applications like Davinci Resolve and Filmora that allow for simple 360 video editing. Does anyone have any advice on which one would be easier for me to simple rotate the initial view 180 dgrees or if there is a simpler script or application that can do this... (note - I'm still able to edit 360 videos in Premiere Pro I just can't use the GoPro Reframe Plugin for edits)

Thank you!
