Hi Peter, I would have suggested you had first tried to startup in Safe Mode / Verbose Mode. To get some feedback about what's happening, you choose to start up while holding down Shift, Command and V: that enters both Safe Boot and Verbose Mode, which spits out some messages about what Safe Boot is actually trying to do as it goes.
Using Safe Mode can help you resolve issues that are stopping your Mac from starting up, or any issues related to your startup disk. If a problem you’ve been having doesn’t occur when you boot to safe mode then it’s a safe bet it’s related to a problematic kernel extension (perhaps faulty hardware that kernel extension accesses), or – and this is more likely – it’s related to a third-party app or service configured to start with macOS.
