After updating Trados 2021 to the recent version, SDL Analyze stopped working. Came across a thread where it said to remove some registries in 'regedit'. Did that, no help. Then did a clean uninstall and install and now the application does not open at all, facing this error "Failed to initialize view "Simple Start View"

Please help
