Solved Error 0x80070005 when trying to install apps from Microsoft Store.

Hi im new to this site and I wanna see if someone had this error before or someone was able solve it because I can't.
The error occurs when I try to install apps from the store, also using the stand alone method doesn't work, the appx installer gives the same error:
"error 0x80070005: While processing the request, the system failed to register the windows.firewall extension due to the following error: Access is denied."
Obviously tried disabling windows firewall and all that but the result is the same.

Welcome to the forum. Error code 0x80070005 means Access denied and it usually occurs because of lack of permissions or missing files.
Things to try:
1. You user account type must be administrator to install apps.

2. Reinstall the Microsoft Store.
Right click on Start.
Click on Windows PowerShell(admin)
Type:
Get-AppXPackage -allusers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
and press ENTER.

3. Make sure you have no corrupt system files that is causing this problem. Open a command prompt as administrator and type sfc /scannow
Pay attention to the scan results to see if SFC found anything it could not repair.

4. Open a command prompt as administrator and type (note the spaces)
dism /online /cleanup-image /restorehealth
Restart computer

Sry for the late response, I tried all you have mentioned and none of that worked, the 2nd step throw a bunch of firewall error permissions (the same as the store) and some apps already in use cannot be stopped. The 3rd and 4th didn't do anything.
I was thinking maybe the problem could be windows 23h2? Because the store was working fine a while ago, and just a month ago or so I forced install 23H2 Update following the guide included in this forum, and im suspecting that messed up all my windows install. In that case do you recommend clean install, or your last suggestion doesn't require wipe out and is a better alternative?

Definitely try a repair install before wiping everything with a clean install.
