Weird Gameplay and Input Delay after console is turned on 15-20 minutes

Hi all,

I am having a very bad gameplay issue since couple of months. I will try to describe what I face.

I am playing on PS5 and generally having 38-40ms ping. I am connected with LAN cable and have fiber connection.

I turn on my PS5 and start playing Rivals/Champions and every time console is turned on like 15-20 minutes(corresponds to 1-2 matches), gameplays starts to feel very very weird. Very huge input delay starts, players starts to act very weirdly, very unusual player animations starts and players move very slowly. This is always same each day. Every day, I turn on console and this weird gameplay starts to happen after 15-20 minutes. 

I tried many things to fix or detect what exactly the issue is but nothing changes. I changed my PS5 with friend and I tried to play on that PS5 to check if any hardware issue exist on my PS5. I changed my internet provider. I applied some configuration on router. But none of these helped to fix this issue. At the first months of EA FC 25, I didn't have such issue and it started almost 2 months ago. Most interesting about this issue is that this stupid issue starts after the 15-20th minutes of I turn on the console. Then whatever I do it is not changing. I turn off the console, restart router etc. but it never fixes on that same day. It gets fixed next day but again after it is turned on 15-20 minutes, issue starts again. On the first match or second, gameplay is ok and I get no issue but later it is horrible

Does anyone else face this kind of same issue? Please someone help me to fix the issue.

Thanks.
