Hello,
Prior to this issue, I had proactively removed my antivirus software and have since been relying solely on Windows Defender in its default configuration. However, I've encountered a problem where Defender also loses its connection, and I'm unable to reestablish it, receiving the 'Error 0x80190001' message.
From my understanding, it appears the recommendation might be to disable the antivirus software before proceeding with certain actions. This situation has left me quite perplexed. And I'm stuck here as well...
