Undefined array key “updraft_restore”

I am not able to restore any of my backups as of yesterday on my localhost copy of a wordpress site

I get the following message when the restore bails: (I have edited the environment-specific path references)

Undefined array key “updraft_restore” in C:\{hidden path}\wp-content\plugins\updraftplus\admin.php on line 5092

There has been a critical error on this website.

Please check your site admin email inbox for instructions.

I did not receive an email, but this may be because of my local work environment.

Can you suggest what can be done to allow me to restore my backups again?
