Denoise AI 3.3.1 Run once only

Have just updated to Denoise AI version 3.3.1.
Can run once as freestanding from desktop icon, or from Start menu and then I have to reboot PC before it will run again.

Same with RAW, TIFF or JPG images.

Anyone else experiencing this?

Edit: Have just returned to version 3.3.0 via full OS partition image restore.
That doesn’t exhibit the same problem.

My PC also same configuration
