Lost packs in PTCG Online after migration

I downloaded and tried out PTCGL a week ago so I could scan my Scarlet&Violet code cards and today I received an email saying I needed to open all packs or lose them on June 5th. I tried to login to the old game only to get the message that my account had been migrated. I had a ton of unopened packs and now I can't get to them.

Is there any way to get back my unopened packs?
