Good afternoon, I'm hoping someone might know the answer

)
I have an Acer Aspire Z3-710. For the last year window update has been running overnight and upgrading when I come to use the PC it is stuck at the windows login screen and I can't do anything other than roll back the update.
Yesterday it updated and I couldn't get into the recovery page to roll back the update, panicked, created a windows USB recovery stick, changed the drive priorities in bios and it wouldn't even boot from this.
That made me think, as the keyboard and mouse are USB I believe that once I have been moved to ver 1909 of windows 10 that my PC is not recognising any USB.
I managed to change the bios so it picked up a bootable drive, rolled back the update, downloaded some software and updated all my drivers. Downloaded the 1909 update and ran that, exactly the same problem.
Once windows ver 1909 update has loaded, PC boots to the windows login screen and I can't do anything, i.e. my keyboard, mouse and touch screen do not work.
I have again rolled back the update.
Can anyone help me at all with this issue?
Many thanks in advance
Gareth
