Thanks all for taking the time to reply. I really appreciate the effort you put in this forum and Calibre itself.

"Wish we always got the details up front like this."
Thanks, I tried to be complete and not waste your time with things I can figure out myself by reading this forum and the helpfile.

"I wonder if there is something wrong with %appdata%\roaming\calibre
That is where settings, PI are kept (the other loc was cache)"
I could not find anything out of the ordinary. Permissions are all good.
What would I be looking for?

"Also, where is your system TMP and TEMP?"
TEMP=C:\Users\Ik\AppData\Local\Temp
TMP=C:\Users\Ik\AppData\Local\Temp

"Have you run chkdsk on your drives? A failing hard drive caused some lag/not responding issues with Calibre for me."
I ran checkdisk for the system disk but it found no errors:

Spoiler:

I ran checkdisk for the external data disk (which is ~3 months old) and was happy to find no errors:

Spoiler:

Looking at the eventlog I found a few bad block warnings but the oldest is 3 weeks ago.
They appear to coincide with connecting older disks, although worrying, that is to be expected of drives ten years old.
That is why I connected them, to back them up.

"If its opening the ebook viewer that is hanging, it is GPU driver issues."
I updated the Radeon drivers to the latest version.
Having most auto-update functions disabled on my system, they were indeed outdated.
The issue still persisted.

Just to be absolutely clear, it's the main program that stops responding.
It takes minutes to start (what it used to do in ten seconds at most).
The ebookviewer works fine but when I open it, the main programs stops responding for ~6 minutes.

I tried to figure out how to disable the GPU hardware acceleration.
To my shame I must admit that even with the instructions you provided, I was in over my head.
I found this description but it did not help so I reverted that setting.
Launch Chrome, “Menu” > “Settings“. “Advanced” option.
“System” section toggle “Use hardware acceleration when available”

Could you please point me in the right direction?
