The lock screen is the trivial item- the in-place upgrade repair failure significantly harder.
Do you have these log files from the upgrade attempt?
The following log files are created when an upgrade fails, and the installation rollback is initiated:
- C:\$Windows.~BT\Sources\Rollback\setupact.log
- C:\$Windows.~BT\Sources\Rollback\setupact.err
Given setupdiag.exe reported nothing, I'm guessing the upgrade failed very early on- too early to create them.
Please have another attempt as I suggested in post #4.
Superficially, the limited view of partitions provided by Macrium (it's not a partition manager) look fine.
Please use Minitool partition wizard (free).

Just by way of comment, noting
johnhoh said all such settings have been removed manually:
N.B.
Home does not have the Group Policy Editor so this is likely to be ineffective in Home.
