Fixing broken links in Apple Music after migrating from iTunes

Hi,

I've migrated my iTunes library (~130GB of music) from a windows PC to my Apple Music app on a Macbook. I've been searching in this forum and managed to add my iTunes library.itl file to Apple Music using some threads in this community. However all the tracks have the exclamation mark in front of them. After some searching I ran into the "fix links" script by TuringTest2. FixLinks - an AppleScript to repair broke… - Apple Community

I ran that script and it only managed to fix some links and it seems to stop working after it runs into an error.

Since I'm not so familiar with scripts, etc. I'm hoping someone can help me how to adjust the script or guide me to a different solution that may help.

The script shows errors that it cannot find a certain track even though I can manually find it in that folder. Given that I have thousands of songs, this script or a similar solution is a lifesaver!

Thanks in advance!
