shader disabled when changing camera forge 1.16.5

I have created a mod which applies x shader to the player after consuming x item for a certain time, but if the player presses f5 to change the camera the shader stops working. The only way I have found to prevent the shader from being deactivated is to load it on all ticks until it is disabled but this greatly reduces the performance of the game. I have also tried to cancel the event of changing the camera but this is not cancelable. Any advice, I've been trying to solve this for several days 😵‍💫
