That's caused by an upstream change in konqueror 20.04.
The introduction page now only works with webenginepart. You can install the
package manually (and configure konqueror to use it as default if necessary) as
a workaround.

Of course you could also set a different start page if you prefer.

Konqueror should work fine otherwise though.

And btw, that's not a regression in an official update. It's how the standard
version in Leap 15.2 behaves (due to upstream changes, as mentioned).
