Hi and thanks for reaching out. My name is Bernard a Windows fan like you. I'll be happy to help you out today.
I understand the issue you have, nothing to worry I am here to help, I know some of these steps are already done, you have just skipped it if you think it will have the same result.
Method 1. Repair Windows Store, Search, Start menu and app:
On Powershell(admin), copy and paste the command below:
Get-AppXPackage | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
Then hit Enter, once the process is done, restart the PC and check.
Method 2. repair Windows Store and update components
Open Powershell with Admin or CMD with Admin (Press Windows key + X then click Windows Powershell(Admin))
Copy each line of command to Powershell then press enter (one line at a time)
net stop bits
net stop wuauserv
net stop appidsvc
net stop cryptsvc
Del "%ALLUSERSPROFILE%\Application Data\Microsoft\Network\Downloader\*.*"
rmdir %systemroot%\SoftwareDistribution /S /Q
rmdir %systemroot%\system32\catroot2 /S /Q
regsvr32.exe /s atl.dll
regsvr32.exe /s urlmon.dll
regsvr32.exe /s mshtml.dll
netsh winsock reset
netsh winsock reset proxy
net start bits
net start wuauserv
net start appidsvc
net start cryptsvc
-Once done restart the device and check.
If none will work from the above solution, I suggest doing an in-place upgrade wherein it will upgrade the device to the latest version and repair all issues without deleting any files.
Note: before doing this make sure to create a restore point: https://support.microsoft.com/en-hk/help/4027538/windows-create-a-system-restore-point
