Acrobat Reader error message AcroCEF.exe Application Error 0xc0000142-pdfs frozen, unable to clear

I use Windows 11.  Updates and drivers all up to date.  I use Acrobat Reader every day to download and print pdfs.  All day yesterday was working fine.  No problem. 

Today, can download and open a pdf but then I get this error message: 

AcroCEF.exe - Application Error 

The application was unable to start correctly (0xc0000142).  Click OK to close the application.

Clicking OK in the error message dialogue box does nothing.  It does not close the application nor does the error dialogue box close.  Acrobat Reader stays open, but cannot print.  Can click Ctrl+P or File + Print, and then OK, but nothing happens; no print job appears in printer status window. 

Cannot clear the error message dialogue box.  If I click on OK or the X in it, it moves position on screen slightly, but stays open, nor does the application close.  Tried closing the Acrobat Reader window by clicking on X at top right and even with it closed, error message is keeps recurring on my screen. Only way to stop it is to uninstall Acrobat Reader.

I have tried:

Update - did not fix it

Uninstall and reinstall Acrobat Reader - did not fix it

Adobe's creative cloud cleaner tool - did not fix it

Writing this post - we'll see ....

Would be grateful for if someone could assist.
