Bug description

Integration of network manager into cinnamon appears to be unstable - switching wireless networks, connecting to and disconnect from VPNs, and stability after any of these events suffer to include black screens and UI lockups requiring cinnamon --replace invocation in a screen session to restore most of the functionality (visual artifacts occur when doing this but at least its usable). The screen session's log outputs are numerous and concerning but the most common messages around the times of the lockups look like:

(cinnamon:1390245): Gjs-CRITICAL **: 06:45:56.515: JS ERROR: TypeError: apObj.item.updateAccessPoints is not a function
_accessPointRemoved@/usr/share/cinnamon/applets/network@cinnamon.org/applet.js:1478:24

Steps to reproduce

Change network connections - starting a client VPN session seems a pretty good reproducer. With Open VPN the packages are:

networkmanager-openvpn 1.12.3-1
networkmanager-vpn-plugin-openvpn 1.12.3-1

Expected behavior

Stable runtime operation

Additional information

No response

Start in applet.js around lines 1364 and 1478, where the reported updateAccessPoints errors occur. Reproduce the problem by changing network connections, especially with an OpenVPN client session, and inspect the Cinnamon log output. Done means network changes no longer produce these errors, black screens, or UI lockups requiring cinnamon --replace.
