No output from cppcheck plugin

cppcheck plugin is enabled (cppcheck version 2.6 installed) on ubuntu 21.10.

Analyze->Cppcheck

All Checks enabled

Custom arguments --enable=all

Only "Check all define combinations not checked"

All sources checked.

Click Analyze

Progress bar slowly progresses.

top in a terminal shows cppcheck is running.

No issues are displayed.

Running cppcheck --enable-all `find -name "*.cpp"` on the same source tree shows numerous issues (variableScope, constParameter, duplicateBreak, etc.)

Clang-Tidy and Clazy work as expected.

Further, cppcheck doesn't show "progress" in the Application Output pane like Clang-Tidy and Clazy so it is difficult to tell what it is "doing".

Let me know if there is further information that I can provide to help debug the "problem".
