AddIn not loaded but shown as active

the last couple of weeks some of our customers reported a strange behavior of our AddIn.
After a reboot of the computer on the first start of outlook the addin is not loaded.
But it is listed under active AddIns. After deactivating the Addin under COM-Add-Ins and
confirming with OK and activating it again, it is loaded and fully functional. It is then
loaded on every start of outlook until the next reboot.
After updating to the latest version of adxloader64 it was reported that everything works now.
After a windows-update yesterday this behavior is back again.
This was reported by customers with Outlook 365 as well as Outlook 2019.
I cannot reproduce this on my developer system but the number of customers is increasing.
On the first start even the constructor of out addin class is not called.
Did you have any reports of such a behavior or any idea where to look to find the reason for this.
Is there any logging for adxloader64?

Kind regards
Nick

Hello Nick,

Once they reproduce the add-in nor loaded, they can get a copy of adxloader.log *before* they turn the add-in off and send it to you. Please send me such a log to the support email address; find it in {Add-in Express installation folder}\readme.txt; please make sure your email contains a link to this topic.

We have seen similar behavior over the last few weeks and in growing numbers as well. We checked the adxloader.log file for anything peculiar but nothing jumped out. Did you figure out what was going on? Is there something else we can try?

Hello John,

If adxloader.log gets updated when you start the host application and it ends with "The instance of the managed add-in class has been created successfully", this means the add-in gets loaded correctly. If it gets disabled after that, make sure you don't get an exception in AddinInitialize, AddinBeginShutdown, OnRibbon* events.
