I just downloaded the eclipse-cpp-2022-09-M2-linux-gtk-x86_64.tar.gz and the help content seems to be broken. I get the error message below in the help browser.
I noticed the same error first when building the Eclipse Trace Compass RCP with the platform integration build I20220804-0700 from today. Then I tried it with some older integration builds and noticed that it starts failing with integration build I20220701-1800
