That suggests a very old version of the DeDRM plugin. And I would have expected that error with calibre 5. You will need to delete the plugins file, "C:\\Users\\Tim\\AppData\\Roaming\\calibre\\plugin s\\DeDRM.zip" and that should let calibre start. Then get the latest version of the DRM removal plugins to install.

The latest version of DeDRM is 10.0.3. It is available at https://github.com/noDRM/DeDRM_tools

Hello,
I deleted the plugin folder, unfortunately calibre still cannot be started.
What else can I do?

Rename your configuration directory and see if Calibre starts.

I wonder if this is yet another example of calibre displaying on a second monitor that is no longer there.

That indicates its crashing very early in the startup process before the Application object has even been fully constructed. If you want to debug further you will need to run from source. Its crashing somewhere between lines 1105 and 1123 in gui2/__init__.py and some print statements in those lines to see exactly where.

Then I suggest you update windows and the drivers in it.
