Hi Tim Van Kaem,
Thank you for reaching Microsoft Community.
May I know which Surface Laptop 4 configuration do you have? AMD or Intel?
Does the bluescreen occurs when you run or open a specific app or do a specific task on the device of t just happens randomly?
What are the accessories or peripherals connected to the device when the bluescreen occurs?
For now, please try running these steps on your Surface Laptop 4 then observe if still the bluescreen error occurs again:
1: Run Surface Diagnostic Toolkit and check Windows Update
2: Update drivers and firmware
Go to Download driver and firmware for Surface, choose Surface Laptop 4 then click Download on the next page.
After downloading, run and install the .msi then Restart.
