Sounds as if you might need mod help. They can if needed manually remove all bits of McAfee . Annoying but this locking up not common from my many uninstalls.
Call support and if necessary request an escalation oif tier 1 support unable to help.
I assume mcpr new download not old one?
THIS SOLUTION LISTED BELOW WORKED FOR ME!!!
The McAfee CleanUp tool (32bit) process was running in background processes area of task manager processes tab so I ended that task and immediately the removal continued and completed with removal complete screen appearing and restart button on that screen.
After restart PC, McAfee Live Safe was still in Programs and Features. ran McAfee Live Safe again. Still hangs up. Looked for the McAfee CleanUp tool (32bit) process was running in background processes area of task manager processes tab so I ended that task and immediately the removal continued and completed with removal complete screen appearing and restart button on that screen. Going to install version 1909 windows 10 upgrade from Windows Updates area and see if it fixes this issue and allows me to remove McAfee from this PC.
Restarted in safe mode with networking. permissions errors when running McAfee removal tool. Also McAfee Live Safe still in Programs And Features.
Restarted in Normal mode and ran McAfee Removal Tool and it now makes it to Removing product MSC state about 75% before hanging for about 2 to 3 minutes and then finishes requesting restart of PC.
McAfee is FINALLY REMOVED FROM THE PC AND DOESN'T SHOW UP IN PROGRAMS AND FEATURES!
Most of the time solutions can be found online. This is the first time I have shared a solution that I couldn't find online. Not something McAfee wants to hear but I am not impressed with the software let alone the trouble the software just gave me on a completely new PC when I try to remove from programs and features. Then I restarted as it would not fully remove from Programs and Features. After restart program was still in Programs and Features. So I downloaded the McAfee removal tool. This is when the hang up occurred. Tried one restart and ran the removal tool again before searching online for a solution.

Such a painful and frustrating process but got there in the end.
