This is happening for about 50% of our team, with some users experiencing the issue & others not - there does not seem to be any correlation with node/chrome versions and having/not having this issue.

Those experiencing the issue can run tests in testcafe if using --disable-native-automation

This issue happens in edge and chrome, headed or headless.
This issue does not happen in firefox.

This seems to have started today.

Any further information I can provide, please let me know.
