Venue 10 Pro Stuck at "rebooting system to make tpm2 settings in effect"

Hi,

I have a few questions

Main one how on earth do you get a Dell technician or start a return I have wasted hours on there site and its rubbish? There on point in having help once the device is in Windows how about before this

I have done a few searches with regards this problem "rebooting system to make tpm2 settings in effect"
and I have found no solution?

What happened was the tablet just started to slow a bit and the recycle bin stopped working I had problems with OneDrive save location, seemed to point to storage problems, so I did a Windows 10 reset keeping nothing and a full wipe it got to the end and had a problem with removing all data and said I should do it again if I was selling the unit then reset to this "DELL" logo the a second flash of "rebooting system to make tpm2 settings in effect" then "DELL" again over and over till I hold the power for a while and turn off

I can not use the 2 options at the start F2 Setup or F12 Other boot devices if I press the volume buttons a loading bar comes up but then just carries on with the loop

On some of the posts people have said about BitLocker - I did not use this

The table was up to date with BIOS A07

I have had it for about 8 months and used it very little twice a week?

I am going to try some other things later and post back if I have success

Thanks

Peter
