Music will not load my iTunes .itl library.

For reasons beyond this topic, I had to delete my user account on my computer (M1 iMac running Monterey 12.5.1) and create a new account. When I try to link Music in my new user account to the old iTunes .itl file, it starts the process, creates the new folder and a Music library (103 bytes) but then stops. In the Music app, it just shows the spinning wheel for hours and days. I've tried it a couple times, then rebooted and tried it again, same result. Any idea what might be happening? Is there an issue with ownership of the iTunes library that needs to be resolved? Thanks in advance for your help.
