Linux Knime, Not opening after installing extensions

Hi, After extracting Knime on Linux it opens without issue.

However if I install extensions when in the Classic UI it crashes out on restart.

It seemed to install ok and open in Modern UI. Too try to get this to work is there a setting in the .ini or ? where i can change it to open in Modern UI before re-starting the application

When it crashes it gives the attached output
knimeError.txt (4.8 KB)

thanks
