Hi, We suggest you to perform clear cache and clear data on gaming apps.
Please follow the given steps.
Go to settings>> Show system apps>> Tap on the gaming app which you want to clear cache and clear data>> Storage>> Clear cahce and clear data. Please perform the above steps for those apps which are not working fine. Please get back to us if it works.
I also had the same trouble and everything has been solved by technical support. I hope you will try to do the same thing.
Anyway, I can say that about half of a year I decided to try something new in order to distract from extra stress and bad mood.
Talking about online games, I would like to mention for you this source Anytime Games where it is quite possible to try some card games and develop mood. I think it will be profitable to you.
