Since your device is already in this boot error state, you can boot Windows successfully after suspending BitLocker from Windows Recovery Environment (WinRE). To perform this task, follow these steps:

manage-bde -protectors -disable c:
- Once the command is executed, exit and restart.
The computer should now start Windows successfully. Once there, you can resume BitLocker protection through the BitLocker Control Panel.
Keep in mind that unless you suspend BitLocker before booting the device, this problem may reoccur. So, to temporarily suspend BitLocker just before rebooting the device, open an elevated Command Prompt window and run the following command:
Manage-bde -protectors -disable c: -rc 1
The above command will suspend BitLocker for a device reboot. the -rc 1 The option only works inside the operating system and does not work in the recovery environment.
Another viable solution to this problem requires you to disable Hyper-V before applying system updates or TPM or UEFI firmware updates on your Windows 11/10 computer.

To disable virtualization-based security on your Windows 11/10 device via Group Policy Editor, follow these steps:
- Hurry Windows key + R to invoke the Run dialog box.
- In the Run dialog box, type gpedit.msc and press Enter to open the Group Policy Editor.
