Diving in to this particular flake above, you find this:

ServerMochaToBackground got a client connection
Failure on testcase: 'test snap_getFile functionality', for more information see the artifacts tab in CI
Error: Found element "[data-testid=\"unlock-page\"]" that should not be present

This error is happening at the connecting / opening of metamask and not during the test.
