I can't play any game since yesterday. I had this problem for a couple of days when the Old Ways update, filed here:

It resolved on 23.04.2020 and I've been playing without problems... until yesterday (06.05.2020). When I was going to start my playing session, it crashed again.

I tried for a couple of games with the same result. Then I tried what I thought was the solution but it didn't work (delete game data and restart by setting PS4 language to English - it seemed to work before, but sure it was a coincidence). Then suddendly it started to work again. I played a couple of games without more problems.

Today, when I was going to start my playing session, it crashed another time, but this time it doesn't work. Nor by deleting data nor by restarting, resetting router, I don't know what to try that I've not done yet.

I can't stand it anymore. If after season 5 update it doesn't become more stable, I'm gonna give up. The problem is not on my PS4 and is not on my internet connection, those factor are fully tested. The problem appears and disappears without changing anything, so I think that it is due to some server update or so.
