Viewer hangs; calibre-parallell is not responding

When I try to open any ebook on Calibre, the viewer program starts with a blank pop-up screen.
After a few moments the header displays " Not Responding"
Then, when I force the viewer to stop (click on the top-right X) another windows pops up with "calibre-parallel.exe not responding".
I've seen similar messages in this forum from years ago, but I can't find a solution.

My calibreversion is 4.13

any tips please?

what OS? if this is windows it is most likely graphics driver incompatibilities. Try updating your drivers.

Thanks for your quick reply !!

I'm using Win10 64b with a Nvidia GeForce RTX2060.
I do have the latest drivers, v445.75 of 03/23/2020

Stay Safe!
Best regards

Ok, something's happening now.
I've started my laptop in SAFE mode, started Calibre and opend a book at random.

Now, the viewer says " Starting for the first time " and opens the book, but only the first few pages or at least alle pages with pictures in it.

I don't get any text.

After closing the viewer's window, I'm getting this pop-up message:
Header: Title - E-book viewer: Calibre-parallel.exe
Content: A fail fast exception occured. Exception handlers will not be invoked and the process will be terminated immediately.

I've tried to open 5 other books, same results

That's it..
Hope it's of use for you?
