Thank you! We're working with our corporate IT team to try and run some tests without the endpoint security software installed, so we'll get back to you if we're able to confirm either way whether this was the cause.

Hi Ed, thanks very much for the response! We do have a couple of endpoint security applications installed - specifically BeyondTrust and Zscaler. Do you happen to know if either of those has caused similar issues in the past? I’ve also created a feedback with a sysdiagnose and a screen recording showing the issue - FB17054509.

Did you ever manage to figure out a workaround for the above? I'm running into the exact same issue with some SPM packages on Beta 5
