I am disappointed to tell you this, but Premiere Elements 2019 is incompatible with Windows 11. You must downgrade back to Windows 10 in order to use that software, or update to a newer version of Premiere Elements.

I have Adobe Photoshop Elements 2023 installed and have the problem, I have not tried renaming the sys file to ascertain if that is a legacy from my previously installed 2015 Elements. I did not upgrade, just bought a new version 2023 Elements (not the bundle). Anyone with a similar issue?

Fixed - Renamed the file pxhlpa64.sys dated 03-09-2013 in C:/windows/system32/drivers folder and restarted Windows 11. PE 2023 seems to work now. It may have been left as a legacy file from the previous PE2015 install. Can now turn on Windows 11 Memory integrity and restart Windows required.

Try uninstalling and reinstalling Premiere Elements 2019.

I unistalled Premiere Elements 2019 and the problem still existed. I found the driver by searching in C: I then renamed it PxHlpa64.old. Rebooted and problem solved. If for some reason I need it in the future, I guess I can change the name back and no longer have Memory Integrity. I say all this so if someone else has this problem and are pointed at Premiere Elements, that ain't it. Whatever it is, you can follow the solution above, granted you do not have a DVD drive that relies on it. Thank you all for your help. Would have never gotten to a solution without it.

Okay... scratch that. The optimism found in my previous post was premature at best. I reloaded Elements 2019 and it said it could not run without the PX file that is incompatible with Windows 11 and that I should contact the provider for an updated driver. Thoughts?
