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?
