When trying to do a back up on my Mac book Pro, I got a popup message "the application 'unlock drive for Mac' can't be opened". I am running Sequoia 15.1.1 The last time I did a back up was in early October.
MacBook Pro 16″, macOS 15.1

See if there is anything here—

typically it is always advised to erase, reformat any new drive to initialize as new—this will remove any proprietary software that may be included with a new drive.
If you’re having issues with a third-party backup app, check for the latest version of the apps, and apply current update as available.
I’d also verify that a restore of your backups works when using third-party backup tools too, or similarly testing if you’re doing something unusual with macOS Time Machine backups. This if you’re planning on depending on that backup for a full restore.
If you are using macOS, Time Machine is built in, and is fully integrated. No need for external apps for that..
