Error 0x80248014 when installing or updating apps - Microsoft Store

Hello.
Windows Store don't work anymore. Nomatter if I try to install a new app, or update one I already has, it breaks off download and give me this error 0x80248014 or sometime 0x80070002. I have searched on google about this, but most answers are about Windows Update, and WU is working just fine, but not the Windows Store. I have read and tried this

and this
Microsoft Store is broken in Windows 10 and I can't fix it

But I'm still without Windows Store, and there are 25 updates in there that can't be downloaded

What can I try? My windows version is 17763.292

I have tried to create another account, but the store does still not work (same errors at download), as I wrote I have tried all the things written in the 2 links. I do make an image every week with acronis, but I only save for 4 weeks at the time, and this error is more than 4 weeks old, so my imageback up is not helping at this time. As Windows Update has been working ok all the time, I have not discovered that the Windows Store was NOT working, as I seldom use Windows Store.

Yes, I have tried to reset Windows update AND windows store.
But I have not tried to do an In-Place Upgrade, maybe this will work? I have to find out tomorrow when not at work

Well, I have now tried to do an inplace upgrade, but the same error in windows store. I give up, and I will do a clean install of Windows 10 in the upcomming weekend

#9 Yes, an elevated prompt (and elevated Powershell when requested).
Yes I can open WS, and browse around, but it can't download anything (new apps or updates to allready installed apps).
I have never changed anything in Group policy, and I don't know what to look for/change in there about WS
