VeraCrypt and Windows 11 24H2 stuck during "booting..."

[arcturus-777]

Hi, this is my first bug report on GitHub. I will try to explain the issue to my best ability.

I run a Windows 11 24H2 system. I updated to 24H2 just about two weeks ago. Then I started the system partition with VeraCrypt as usual and everything seemed to work perfectly fine until the point where you have to do the (booting) test, right before you start the real encryption of the system partition.

The system starts and the VeraCrypt bootloader menu appears as usual, I enter my password, VeraCrypt confirms "OK" and then it prints "Booting..." and nothing happens. You are stuck at this point. Soft-Reset does not work, but a hard reset works. You can then skip the VeraCrypt bootloader via ESC and the system boots normally into Windows where I then chose to not go through with the encryption.

Expected behavior

I expected VeraCrypt to boot into my system as usual.

Observed behavior

After entering the correct password VeraCrypt confirms "OK" but is then stuck showing the prompt "booting...".

Steps to reproduce

1. Open VeraCrypt and start system partition encryption process
2. Set password, encryption alghorythm etc. (I've used the standard settings and did not change anything)
3. Provide randomization data by moving the mice
4. Create and burn rescue disc
5. Start pre-boot-authentication test
6. Wait for VeraCrypt Bootloader to appear
7. Enter correct password and confirm -> VeraCrypt shows "OK"
8. VeraCrypt shows "booting..." and nothing happens.

Your Environment

-Windows 11 24H2 (64bit) -> running in legacy MBR mode
-VeraCrypt recent version 1.26.20 from February 3rd

I use VeraCrypt for many years now on the exact same system. It worked flawlessy on all Windows 10 and Windows 11 versions until the 24H2 update dropped.

If anymore information is need to help with troubleshooting, please let me know. I am happy to support you.
