Hi All, I've confirmed that there is a performance issue after upgraded to 4.18.23050.5, the website loading time in the first time access from a 3rd party browsers are extremely longer than before.

I've raised this issue to Microsoft support and asked them to re-open the previous ticket.

We are seeing same performance issue in chrome after update to 4.18.23050.5. Have raised with MS but no update. If we roll engine back to .3 don’t see the performance issue, but it seems to auto-update back to .5. Anyone know how to stop it auto updating, just the engine? Or any better suggestions? Thanks

    I rolled back the engine to version .3, which resolved the performance issue. However, I noticed that the engine automatically updates back to version .5. To prevent this from happening, I made changes in the Windows Registry Editor (Regedit) to disable the auto-update feature. These changes have successfully prevented the engine from updating itself, allowing me to maintain version .3 and avoid the performance issue.

    We too have started seeing the same issue.  If we offboard devices from Defender the problem goes away.

    Have either of you heard back from Microsoft regarding this issue?  Just before i raise a case with MS myself.

    Thanks

        Thanks for the update, my Microsoft case is still sitting with the team. Any workarounds provided by Microsoft by chance?
