Tags and Playlists disappeared (after technical upgrades to CX and EX)

Having just had the Antipodes Audio OLADRA technical upgrades to my CX and EX, when setting everything back up again, all my tags have disappeared and playlists.

Not sure why this is so and really need these tags. I’ve applied about 40 different tags to over 21 thousand tracks which basically helps me account my library content. Not having these just throws everything in a pot

I’ve tried to see if I can find my Roon backups but for the life of me I can’t figure out what folder they would be in
