Apple QuickTime Player

So, just recently I've been unable to import MP3 music files onto my Pro Tools First Program. In the past I've been able to, but as of late I had this issue where an error message will pop up and say that I need to install Apple QuickTime Player before I can import the file.

The question that I have is: Why do I need to install QuickTime player when I already have it installed?

It just doesn't make any sense. That brings me to my next question

Q: Do I need to update to macOS Big Sur in order to update QuickTime player?

But I feel like my Mac book pro might not have enough storage for it, and it will likely take up all my storage space.

I don't have a lot of stuff on my MacBook Pro yet except for a couple of downloaded music, and I've only had my MacBook Pro for only a year.

I've did some research and try to do some simple steps, but don't want to do anything that might ruined my MacBook. Also I don't want to lose any of my contents or work. I thought that I should reach out to Apple Support before I decide to do anything else, because this little error is causing me to not getting any work done. I would like to get some explanations or support as soon as possible.

Thank You.
