Browsers (Edge/Chrome) freeze for about 2-2.5 minutes randomly!

My browsers (both Edge 87.0.664.55 and Chrome 87.0.4280.88) freeze for about 2 - 2.5 minutes randomly! This is a fresh clean install of Windows10pro and did it before with the last install as well (I have all updates etc for win10pro 20H2, and latest Edge and Chrome.)

It's always 2m13s-2m27s that it freezes. I can't switch tabs within the browser then or open tabs. I can move the window around or close it (thou I can't open the same browser till after the 2min+.) I can use the rest of the computer fine it seems, and even open/use a different browser fine. It will do it when closing a tab or just browsing through a webpage. I can't figure out what is causing it. Tried both browsers with and without uBlock Origin to see if it was ads causing this but doesn't seem to make a difference.

No errors I can find anywhere.
Any ideas??! This system I just built for my mother and she can't use it like this (its an older i5 750 with 8GB RAM, GTS8800 and three SSDs in it, but totally fine for her browsing etc.)
Thanks all!

Well I installed Firefox (83.0) and it doesn't freeze at all yet. So its the Chromium based browsers that are doing it so far.

I am having the exact same issue. Its after the most recent Chrome update. I cannot figure out a fix. Has anyone managed to fix it?

This worked for me. Went to Event Viewer and saw these warnings under Windows Logs > System : -
The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID

Opened "Component Services" app and added my user in "My Computer" even though "Everyone" was already there.

Everything is fine now.

Can you provide specific instructions on what you changed? I don't want to change the wrong setting. Thx

This usually happens when there is insufficient permission given to the CLSID and the APPID. I suggest you to follow the steps mentioned below to provide the permissions:

Note: Important this section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

Follow the steps to take backup of registry.

Press Windows key + R, to open Run box.

Type regedit and click on OK. This will open Registry editor.

Now, navigate to HKEY_Classes_Root\CLSID\*CLSID that appeared in the error message*.

Right click on the CLSID, click on Permissions and click on Advanced.

Click on Change beside owner, type Administrators, then click Check Names and click on OK.

Click on Add and click on Select a Principal.

Type Administrators, then click Check Names and click on OK.

Click on Full Control and click on OK.

Click Apply and then click OK.

Now, navigate to HKEY_LocalMachine\Software\Classes\AppID\*APPID that appeared in the error message*

Right click on the APPID, and repeat the steps from 4 to 9.
