OneMore: Update to OneMore v5 on OneNote 2209 causes OneMore not to appear in UI

Describe the bug I had OneMore 4.17 x64 installed. I upgraded OneNote to the latest 2209 x64. OneMore was accessible via the ribbon and context menu.

I then upgraded OneMore to v5, using the msi (the auto update appeared to work (OneNote closed automatically), but the OneMore version was unchanged when OneNote was relaunched).

When relaunching OneNote, OneMore was missing from the UI. The addin was still enabled in the COM addins window, but there was no ribbon (either visible, or in the ribbon customisation UI), and the OneMore context menu entries were missing. In effect, the addin was disabled…without having been disabled.

To Reproduce Steps to reproduce the behavior:

1. Have OneNote 2209 installed with OneMore 4.17
2. Close OneNote. Install the OneMore 5 update
3. Open OneNote

Expected behavior The ribbon and context menu UI should still be active

Screenshots If applicable, add screenshots to help explain your problem.

Environment (if applicable):

• OneNote Version: 2209 15629 64 bit, from the Office insider preview
• OneMore Version 5

Additional context I uninstalled OneMore v5 and installed v4.19 - the ribbon and context menu were restored, so I have a workaround.
