Microsoft Access DBEngine.OpenDatabase() breaks for Network-Paths – Error 3050

From Microsoft:

This is due to today’s (Patch Tuesday) update to Office. The problem
was introduced by a security fix, so it impacts all active versions of
Access. We are working on a fix, and will deliver it as quickly as
possible.

The update has only been set to automatically update a very small
percentage of users, and it looks like we will be able to pause
automatic updates, so it will not propagate.

There will be a page added to the

Fixes or workarounds for recent issues in Access (microsoft.com),

which will then be the place to go
for updates.

These are the updates that introduced the problem:

KB 5002104 for Office 2013
KB 5002099 for Office 2016
Office 2019 Version 1808, build 10381.20020
Office LTSC 2021 Version 2108, build 14332.20204
Microsoft 365 Apps:
    Current Channel Version 2111, build 14701.20248
    Monthly Enterprise Channel Version 2110, build 14527.20340
    Monthly Enterprise Channel Version 2109, build 14430.20380
    Semi-Annual Enterprise Channel (Preview) Version 2108, build 14326.20692
    Semi-Annual Enterprise Channel Version 2102, build 13801.21086
    Semi-Annual Enterprise Channel Version 2008, build 13127.21842

If you did get updated to one of those builds, the only solution
currently is to move back to an earlier build in the channel.
