@benakaget: As your query relates to a third party app/service, I am sadly limited in the advice that I can provide from this position. What I would suggest is reaching out to the developers directly to enquire about the minimum requirements for running the emulator on your Tab S6 Lite (or Android tablets in general), along with any compatibility issues you might be experiencing.
Alternatively, please check the Google Play Store for any available PS2 emulators, which will be optimised for use with your Galaxy tablet.
