No 'go back' option on security update from 4 days ago

I'm trying to roll back security update KB5074109, which has made it impossible for me to use InDesign, which is the main programme I use for my job. It's a known issue - all my files are backed up on Dropbox/OneDrive and the update has changed how file locking / write permissions work (InDesign can still open files (read access), but failed when saving (write/overwrite), which triggers Error Code 2) - and I can't afford to be unable to work until Windows gets around to fixing it.

Only issue - the update was installed on the 16th and it's now the 20th. Only 4 days ago but there's no 'go back' option in settings to uninstall the update - it's not even greyed out, just completely not there. Please help, thanks!
