Missing Plug-in after PE 2022 crash

I use the Topaz DeNoise Ai and Sharpen Ai plug-ins with PE 2022.  They both worked fine until PE crashed yesterday while I was processing an image with the Topaz DeNoise Ai plug-in.  When I restarted PE 2022 only the Sharpen Ai was visible. The standalone Topaz DeNoise Ai continues to run without a problem, suggesting either a corrupted plug-in or a problem with PE 2022. I have done the following in an attempt to resolve the problem:

1. Downloaded and reinstalled the plug-in.
2. Done a thorough clean of my system to remove junk files and other temporary files, followed by a reboot and rerun PE;
3. Uninstalled Topaz DeNoise Ai, again done a thorough clean of my system to remove junk files and and temporary files, reinstalled Topaz DeNoise Ai, including the plug-in;

None of the above resolved the problem and the only plug-in listed under Topaz on the Filter menu is Sharpen Ai.

I still have a copy of PE 2019 on my system.  When I ran this, both the Topaz DeNoise Ai and Sharpen Ai plug-ins are listed under the Filter menu and both work correctly (see attached PDF images).  This suggests that the issue lies with PE 2022 rather than with the Topaz plug-ins.  To resove this I tried the following:

1. Repair PE 2022 by rerunning the installation program;
2. Uninstalled PE 2022, again done a thorough clean to remove junk and temporary files, restarted the computer and reinstalled PE 2022.

Neither of these actions resolved the problem and Sharpen Ai is still the only plug-in listed under the Topaz menu under the Filter heading.

I am at a complete loss as to what has caused the problem.  As both plug-ins are visible in PE 2019 and work fine the problem appears to be with the installation of PE 2022, either in the registry or one of the many folders / files the program relies upon to manage plug-ins.  I would appreciate any assistance you can provide as to the source of the problem and how to resolve it.
