Win10 app store can't open?

To delete the cache, first find the right location. The path of the Win10 app store is:
C:Users(username)AppDataLocalPackagesMicrosoft.WindowsStore_8wekyb3d8bbweLocalCache
It should be noted that if you want to enter the above AppData folder, you need to display the hidden file, you can do it in the file explorer. ; View the ” tab, find “options", then select “Show hidden files, folders, and drives in the “View” tab of the folder options.

After entering the LocalCache folder, delete all the files and folders inside (the cache file will be rebuilt, delete it anyway). At this point try to open the store app, the problem should be solved.
