Libre Offfice not running

Recently installed Ubuntu Studio 25.10. Running it for the first time, I selected tabbed interface.
Opening a pdf drawing caused the Libre Draw to stall and not run.
I started in Safe mode and used both reset to original settings functions - no change. Removed all the apps using Discover but they stayed under the menu bar
Installed 25.8 and this won’t open at all.
Added earlier version but this won’t open either.
Saw some folks suggesting a user profile issue, so created a new user and tried to run Draw - won’t open.
I’m assuming there is a config file somewhere that’s causing this but as a recent migrator from Windows I don’t want to screw the install up! Although aware that a full re-install might be my only option at this point.
