I'm having a similar problem with installing the BCAT and I have access to the discord my time is synced and I used the BCAT tab. I tried asking for help in the server got no answer. Is there something I'm missing?
On 20.0.0 there's more bugs as for the games not starting could be sigpatches but I would definitely downgrade for now. Just be careful doing that my emunand bricked after downgrade.
I think it's a known bug on current firmware. Are you on 19.0.1? Tinfoil hasn't been updated to support that firmware. It still says it for me I can start a game and it plays.
Recently recovered my bricked switch and can't find the package1_keys I'm unsure of where to progress with this?
I do not have the original keys as it was years ago. I used the doner method to revive the switch.
