Ryujinx launch error

Hello all,
First, thank you for Retrobat!

Launching a Switch game with the latest Ryujinx fails from Retrobat, with the error below. Retrobat sees the games, they are in the gamelist, but Ryujinx shows no games, however, if I open Ryujinx directly from the emulators folder, it works fine without problems.

Any ideas?

Hello
Have you followed the instructions from the changelog 6.3.1 ?

- Move RPCS3 dev_hdd0 folder to saves\ps3\rpcs3\hdd_0 (you need to cut/paste when upgrading, if you want to keep the current folder in emulator directory, delete saves\ps3\rpcs3\hdd_0 folder)
- Move PPSSPP memstick folder to saves\psp (you need to cut/paste when upgrading)
- Move CEMU mlc01 folder to saves\wiiu\cemu\mlc01 (you need to cut/paste when upgrading, if you want to keep the current folder in emulator directory, delete saves\wiiu\cemu\mlc01 folder)
- Move XENIA and XENIA-CANARY content path to saves\xbox360\xenia (you need to cut/paste when upgrading, if you want to keep the current folder in emulator directory, delete saves\xbox360\xenia folder)
- Move Ryujinx portable path to saves\switch\ryujinx (you need to cut/paste when upgrading, if you want to keep the current folder in emulator directory, delete saves\switch\ryujinx folder)
- Move Vita3K content path to saves\psvita\vita3k as default(you can still use a custom path)

I had not followed that, that was exactly it, thank you!
