LR from a Time Machine restore

I purchased LR and ran it on my laptop until my laptop died and I had to get a new one. I loaded LR onto the new computer from a time machine backup, but now I get an error message saying "Adobe LR is damaged and can't be opened. You should move it to the trash." The company says they no longer support that version of LR. Any ideas for a workaround? Thank you. I am running on a Mac with Apple OS Ventura 13.5
