In my case, I have the front end database running on users' laptops, so I needed to rollback all the users to Access 2013 (Note there is a 32-bit and a 64-bit version. I needed to go with 32-bit). Not sure if you have a similar setup.
I know what you mean about IT departments controlling all updates, revisions, etc. I work for a very large corporation with many levels of bureaucracy. It's taken me since Nov 2019, when the database corruptions started happening after the Windows 10/Office
2016 upgrades,
to get them to review my numerous requests and rollback my users to Access 2013 32-bit. I also had to enlist my boss, his director and the CIO to assist me. IT will finally be starting the rollback next week. Persistence pays off.
They will be moving to a new system in the future, but I have to keep this Access database working in the meantime.
