May be read this. It could be that your hardware is too new, or it could be the RAM slots used, and maybe have a read here. This thread shows success by using a dedicated gpu for the install. Another issue found during my research is a need to patch certain intel igpus. Hope these help.
Other things to consider. Try disabling secure boot, any non-essential hardware as these may cause issues based on various other posts I have read with this issue.
If it were me, I’d try and get the install to complete with a dedicated gpu of any kind to bypass any igpu issue and then see if you can access the GUI with the dedicated gpu removed.
