Upgrading to Windows 11 with (pre)existing VeraCrypt system encryption

I've tried upgrading a laptop to Windows 11, with an existing VeraCrypt system encryption. I decrypted the partition and removed the system encryption first, then tried the update. It always failed with error 0xc190012e. I couldn't find any details about that error code, or helpful advice. I've tried a bunch of generic stuff (upgrading via either Windows Update or Windows Update Assistant, chkdsk, sfc /scannow, safe mode with networking, and probably some more), but none of these resolved the issue. tldr: Delete or rename C:\Users\Default\AppData\Local\Microsoft\Windows\WSUS\SetupConfig.ini after removing the system encryption. A few more words about this: There's a file C:\Users\Default\AppData\Local\Microsoft\Windows\WSUS\SetupConfig.ini (documentation) which VeraCrypt creates when encrypting the system partition, with the following content (for me at least):

[SetupConfig]
ReflectDrivers="C:\Program Files\VeraCrypt"
PostOOBE=C:\ProgramData\VeraCrypt\SetupComplete.cmd

After removing system encryption, the file only contains

[SetupConfig]

but still exists. Removing or renaming this file allowed me to upgrade and re-enable system encryption without further problems. I've tried it on another (desktop) machine to verify - ran into the exact same problem, which went away after removing that file. Edit: I've opened a bug report at VeraCrypt's repo.
