I was having this problem recently also. Depending on what year your Macbook Pro is... if you have the power (charging) cable plugged into the left side. I would recommend first trying to move the power to the right side of your laptop. This is apparently a known issue with 2019 MBP's especially with the 16 inch model. Also, I found that because i had purchased a magnetic adapter online for my power cable, when i removed it, the high kenel task magically disappeared. Id recommend trying the same!
