Took me a few hours to figure this out, figured I'd pass it along. Forgive formatting, I'm on mobile.

How to Bypass Bitlocker for Crowdstrike BSoD

Only use this if the Bitlocker key is lost.

From the Bitlocker screen, select Skip This Drive. A command prompt will appear.

Type bcdedit /set {default} safeboot network and press Enter.

Type Exit to exit the command prompt, then select Shut Down

Hardwire the device to the network

Navigate to C:\Windows\System32\Drivers\Crowdstrike and delete C:\windows\system32\drivers\crowdstrike\c-00000291-*.sys

Win+R to open the Run menu, then type msconfig and press Enter

Go to Boot

Uncheck the box for SafeBoot

You will receive a warning about Bitlocker. Proceed.

Click OK and you will be prompted to restart. Do so.

Any system without network unlock usually requires a TPM PIN/PW every reboot. Your instructions (when read a certain way) imply that the command also bypasses the encryption without fetching a recovery key from the TPM or DC.

My home network (ISC DHCPD) behaves this way - either I type the TPM key or I type the 25-char key.
