Secure Access app on Mac OS Catalina

Hello everyone,

I have a Flash Drive (CZ45 64GB Ultra) where I have encrypted my files through the Secure Access software.

Since installing Catalina, the app cannot be run anymore. I searched the SanDisk website for an updated version, which, when run, asks me to be installed in the pen drive itself.
I am concerned this might delete what’s currently in the pen drive, so I didn’t proceed. I also have no guarantee it will work on Catalina.

Is there an official guide / solution for people that cannot run the old software on Catalina? Thanks.
