Experiencing severe lag spikes for the past two weeks on PS5

Internet is fine and other games run exceptionally well online. I use Wi-Fi 5GHz band with a stable 300mbps through an up to date Xfinity Gateway. I recently began experiencing hard rubberbanding in Deathmatch and Role Queue games. Other modes like Arcade and Gauntlet work fine. When the lag spikes occur the latency readings stay around 50-60ms as well. I don’t really understand if it’s a client issue or a server issue but it’s making the game quite hard to play

Unfortunately, the only way to find out where a lag spike is occurring is to use PC software that tests the connection.
