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, apps and taskbar:
On Powershell(admin), copy and paste the command below:
Get-AppXPackage | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
Method 2. repair Windows Store, apps 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.
