"Sleep Wake failure in EFI Failure code:: 0x00000000 0x0000001f" Macbook Pro 16-inch 2019

info:

processor: 2.4 GHz 8-Core Intel Core i9

memory: 32 GB 2667 MHz DDR4

graphics: Intel UHD Graphics 630 1536 MB


I previously had this problem with Catalina. After I updated to Big Sur the problems stopped. I recently updated to Big Sur 11.5.1 from 11.4 on 7/29/21. Since then every time my mac has powered off/on I have received this failure. Is anyone else having this problem or know a way to fix it or even know why it's happening?

MacBook Pro 16″, macOS 11.5
