Did you manage to fix it?
I've been having the same problem on a macOs Big Sur 11.6: I can't get the Tidal pluggin to find the folder with the update. I've tried everything I've found on the forums with no result.
Even now, installing Pulsar I thought I could get it to do it, but I haven't been able to do it either.
I'm currently using the old version 1.7.8 and the only way I've been able to get it to work is by following this thread
