What should I check first if I see symptoms of the Microsoft Store not opening?

First, proceed with the ‘Completely restart your PC’ step. Temporary driver and service errors can often be recovered just by restarting. We recommend that you avoid changing multiple settings at once and check to see if your symptoms change after each step.

How do I check for the possible cause ‘Store Cache Corruption’?

If there is no change in the first step, compare in order through ‘App recovery/reset or using official reinstallation’. If symptoms disappear immediately after certain actions or the conditions for their occurrence change, this can be an important clue in narrowing down the cause.

Microsoft Store won't open: When do I need a professional check?

Even if you follow the above solution steps in order, if the Microsoft Store cannot be opened repeatedly, or hardware abnormality signals such as a burning smell, abnormal noise, overheating, or failure to recognize parts appear, we recommend backing up important data and performing a professional inspection.
