The Preview app will no longer open a jpg on MacOS

The Preview app will no longer open a jpg on MacOS. "Couldn't communicate with a helper app". The Preview app will no longer open jpeg … - Apple Community was closed so I don't expect the Community will be able to help. According to Apple the problem is solved but I need more info. Did the user buy a pc to open their jpg? If I need to restart every time I want to open a jpg a Windows box makes sense, luckily the 16" MBP M5 I was waiting for wasn't for sale this fall! Unable to upload a song to iPhone, the multiple apps I bought to replace iTunes are a lot better than Apple Music but I still need an iTunes replacement that works with my Apple iPhone: is iTunes on Windows the solution? Mail no longer functions, I had to delete my offline accounts and I just reread a number of emails I wish were marked read the first time I read them, there must be a computer that can play a song without stuttering like Apple Music, open a jpg with little difficulty and receive email that I can literally read. I'll keep searching for clues on how to open a jpg on the new MacOS but I have a lot of work open, that will definitely waste my work day. I've bled in seven colours for over 25 years but maybe I need to think differently. Does a restart make Preview work again? Anyone else wondering how to open a jpg on Mac?
