Personally, I think it's too soon to blame possible custom hardware inventory. Because it looks like, at least for this specific machine and this specific log, it can't even do heartbeat ddr:
"<![LOG[Inventory: Opening store for action {00000000-0000-0000-0000-000000000003} ...]LOG]!><time="16:27:04.146-300" date="09-28-2020" component="InventoryAgent" context="" type="1" thread="1380" file="datastore.cpp:176">

I suggest first confirming how many devices have stale heartbeat, hinv, or sinv. I forget when it was added to the console; hopefully it's there in v 1810. In your console, go to "monitoring", then "Client Status", then "Client Health Dashboard". one of the charts is for "Scenario Health"; which lists how many are successfully doing multiple client actions, like policy requests, heartbeat, hardware inventory, and software inventory.
