PP Beta Render is so slow

I am trying to edit a video from Kauai from last summer.  The issue with the beta that I have run into is with DJI Air 2S drone footage.  When I play it back it keeps glitching and does not play smoothly.  But before anyone starts asking, "Well, what computer are you using, graphics card, amount of RAM, and blah, blah, blah" I can play the same footage in the latest PP version and it plays back smoothly.

Then this happened.  I was getting so mad at how slow and glitchy the playback was, I decided to render a portion of the video.  I set the In and Out, went to file, export, set the correct video format and pressed enter.  Now if I render the same footage in the latest PP version, it would take a few minutes.  However, when I went to render in the Beta it said it was rending 228 or 409 audio previews and it was going to take over 24 minutes.  The audio previews thing struck me as odd because there is only one audio track under the drone footage.

So why is the Beta so slow to render and why is it having issues rendering or even playing DJI drone footage?  The standard video file for my drone is mp4.

I sat her for over 20 minutes and I'm down to the last 3 minutes or so.  I cannot wait to see how it turns out.
