I have been experiencing this since FIFA 20. Every single game since then, on PS4, PS5 and Xbox. At least once a week on squad battles, the game will kick me whilst I am mid match. It mostly happens in the second half. It is not an internet issue as it doesn’t disconnect me from the EA servers. It is a bug.
I have asked many people online about this and they all say the same thing. Many are experiencing it for the first time on FC25, but I have been experiencing it for years. If you search “Squad battles crashing/crash” online, many reddit forums will appear of people talking about this. I asked on futbin too and people relate. I cannot fathom how this hasn’t been found or patched yet. It’s quite literally game breaking and really doesn’t give me motivation to play the game.
It will kick me and give me a 3-0 loss, making it impossible for me to get points for the week. Often I’ve missed out on elite spots due to this. It has made objectives like icon swaps, daily play and evolutions very hard.
