Cannot access windows 11 after update ubuntu 23.04

Question

I just did an ubuntu version update this morning (from 22.10 to 23.04) via the updater software application. after that I wanted to access my windows installed on the same device. the first time I was able to access, but some files that I previously opened in ubuntu could not open. and after that my laptop went into a blue screen and kept restarting when I try to reboot.

I have tried inserting a bootable USB to enter safe mode, but my computer cannot enter the installation menu
I have uninstalled my ubuntu 23.04 and reinstalled ubuntu 22.04
I've been waiting for Windows to do its own 'Preparing Automatic Repair', but the process stops halfway and returns to the blue screen and then reboots

Microsoft create a nice webpage for this error (with not much info), see: UNEXPECTED_KERNEL_MODE_TRAP. the real solution is re-install Ubuntu (and maybe Windows ) But first decide if you want version 23.04 or 22.04, do not mix them, when you are a new user!! — Luuk, Oct 14 '23 at 08:26
Does this answer your question? Unable to boot into Windows after installing Ubuntu, how to fix? — karel, Oct 14 '23 at 12:41

You probably need to tell your PC EFI settings to boot the Ubuntu GRUB menu, not the EFI Windows boot. After booting Linux, if you do not see a Windows section in the initial grub boot menu a "sudo update-grub" command in a terminal to make sure to trigger the Windows bootloader detection mechanism of the Linux boot manager grub.
