WD MyPassport 500G will not unlock on Mac OS Catalina

My Passport 500 gig will not unlock after updating my macbook pro to OS Catalina. I get error message:
“DriveUnlock” needs to be updated. developer of this app needs to update it to work with this version of macOS. Contact the developer for more information.
When i run the update i get a new error message:
Drive is locked, unlock your drive and click continue to update.
Does anyone know how to solve this?

Best regards
