Game keeps pausing and unpausing.

Hello GGG, I am playing on Playstation 5 pro. Game runs great until I created a cast on crit build with blood mage. It creates a lot of lagging due to frost wall. The explosion it creates makes a huge impact on lagging. After that, I recently got this bugged that keeps pausing and unpacking the game everything I play it blood mage. Other char doesn't do that....is this a network issue?

Playing Blood mage with CoC frost wall too. can confirm it breaks the game from time to time. I had to blink out to get the frost wall outside my screen to reduce lag
