Confirming.

I think it expects something present under the registry key
"HARDWARE\DEVICEMAP\PARALLEL PORTS"

With the stupid hack below, which populates it with wrong entries(!!!), the
application starts for me. Also just just disabling mountmgr.sys prevents the
crash. Maybe someone who knows more about parallel ports might have a look at
it.

I tested to create symlink for lpt port to /dev folder.
Command used: sudo ln -s /dev/null /dev/lp0

After this i checked registry and there is one entry in:
HARDWARE\DEVICEMAP\PARALLEL PORTS

With this change realterm starts. 
On start there is message complaining about invalid handle but that does not
prevent starting.

Question related to that key in registry.
In case there is no lpt port on system, is there need for the PARALLEL PORT key
in registry?

In Windows 11 & computer without parallel port, this key does not exists in
registry.

Windows 11 does not have PARALLEL_PORTS key in registry so i tried to remove it
in Wines registry.
After removing the key realterm started.

Steps used:

1. Open regedit 
2. Delete key PARALLEL_PORTS at HARDWARE\DEVICEMAP.
3. Leave regedit open
4. Open another terminal 
5. Start realterm
