Working with a video file that was missing metadata in Premier Pro

I do video production at a live music venue. We live stream many of our shows and record them via OBS. We then take those files, trim them down, and post to youtube. We recently had our PC crash on us while we were recording, so the file didn't write correctly. I was able to use recovery software to fix the missing metadata and make the file usable.

The audio is as it should be, the video on the otherhand is slowed down to about 50% when opening up via VLC media player. The file cuts off when the audio does. Which is what the file duration in windows explorer shows the video to be as well.

When I import the video into Premier Pro, the video duration is doubled and plays at the proper rate. It's just extremely glitchy and seems to be mixing up and adding random frames of the video to other parts of the video. I have no idea if I am explaining this correctly, but any help on working with this file would be greatly appreciated.
