Slow editing running PC Insta360 Studio Desktop?

I recorded videos using my insta360 x3 and today is my 1st time trying to edit the videos. I realized it's running very slow.

For some backgrounds, my PC works fine using OBS Studio, iphone camera plugin while recoding desktop. Then, use shotcut to edit the videos without any lags for large video files.

When using insta360 studio on my PC, it appears to be very slow. It's recorded using this micro SD Card below. I've checked to ensure it's compatible with insta360 and many users on the Q&A confirmed it runs fine.

Any advice I could following to use Insta360 Studio on PC to run fast?
