Hi,
Thank you for posting in Q&A!
According to the screenshot, the network connection problem is caused by the "crowdstrike" software.
May I ask that the screenshot is after or before you uninstall the crowdstrike? What's the specific error message of Network connections Diagnose show after you unintalling crowdstrike?
If it's the same error message, the problem is with crowdstrike. Maybe you didn't uninstall it thoroughly.
Since it's a third party software, please refer to crowdstrike technical suppport team for more professional advice, thank you for your understanding!
