PS. If you get around to un-installing Brave, see what “breinersj” did:
“Can't watch Amazon videos - widevine issue - #5 by breinersj”
“completely uninstalled/reinstalled Brave (which didn’t work) and then uninstalling Brave, removing all directories with any Brave information, then reinstalling”
And, try CCleaner by Piriform
“https://www.ccleaner.com/ccleaner/download?pc”
in addition to watching what the computer’s networking is doing, via NetLimiter 4:
