Premiere Rush keeps exporting corrupted files

I have been working with Premiere Rush for about a month now and there was never a problem until recently. Now every time I export an edited video, I'll go to check it in VLC and either get a partial video that claims to be the length of the full video or no video at all. This has even affected videos that I had no issue with exporting last week. Now I can't export any content unless it's unedited. The footage comes from an iPhone 10 and is transfered to my PC running Windows 10 via cloud storage. I have tried the following to fix the issue:

• deleted a project and started over from scratch
  • (didn't work)
• tested every saved graphic in a video to see if one of them was corrupted
  
  • (exported video cut off at random points each time or just didn't play at all)
• changed frame rate from automatic to a preset
  • (didn't work)
• exported project assets by themselves to check if they were corrupted
  • (they exported without issue)
