Premiere Rush won't open my MOV file

Every time I try to upload an MOV file to Premiere Rush, I get a message saying the program was unable to open the file. Despite the fact it's a screen recording created through Quicktime/Apple and I read that all Apple files are supported. 

For more background, I have attemped to do this on a MacBook Air circa 2014 and an iMac from 2019 and get the same results.
