Next steps:
Look in Reliability History/Monitor and Event Viewer.
The objective being to find and identify any error codes, warnings, or even informational events related to the update failures and/or Microsoft Store.
Start with Reliability History. Much more end user friendly and the timeline format may reveal some pattern.
Event Viewer requires more time and effort to navigate and understand.
