THPS 1+2 - please run the game via epic launcher, internet connection required

Hello. Few months ago THPS 1+2 from Epic worked perfectly fine on Steam Deck. After few months I've tried yesterday to play but while running white window appears and shows error "please run the game via epic launcher, internet connection required" (I have HGL in Polish, that error is not 1:1 in English) and game crashes. Ofc, Wi-Fi is on with stable internet connection. I've tried almost everything but uninstalling, which I really want to avoid. Any ideas?
