Can't play nor color grade video

Hi. I'm currently using Davinci Resolve 17 Beta on a Mac.
I had some issues with codecs so I upgraded from 16 to 17.

I shot my video with FX9 and Sony Alpha7SIII(MFX files and MP4 files). I also downloaded Apple Pro Video codec pack just to be sure.
There seems to be no problems with my xml file. I exported from Adobe Premiere. I can bring all my media files but somehow I just cannot play nor color grade the clips.

I attached my screen so that I can show you guys what kind of problem I'm having.
Could it be because I'm using Catalina OS?

Free or Studio? MXF files are only supported by Studio.

Free version
But I had no problems with MXF files in 16 free version
I can bring all my media but just can’t playback the clips

Is that an Intel Mac or M1?

You can post a short clip for testing. I have no problem opening clips from the Sony FX9 in Studio 17.

It’s Intel

I fixed the problem
I upgraded it to Studio and everything works just fine
It must have been the verison

Thanks everyone
