Bridge crashes and freezes

Afterupgrading to V 11.1Bridge is virtually unuasable.

1. Bridge unable to perform simple function like Kewording. Will freeze after 2 inputs.

2. Open a RAW file in ACR and you have to close Bridge otherwise the system crashes.

3. Photoshop and bridge cannot be open at the same time. System freezes

4. Any Batch editing process is impossible . eg Batch renaming

There is more but this is a sample of Bridge having no functionality after upgrade.

Prior to the upgrade the system ran perfectly!!
