This old thread the User has the exact same issue as you do when he activate SVM in BIOS using a Ryzen 2400g processor it won't boot into Windows: https://linustechtips.com/main/topic/1078595-windows-10-wont-boot-when-enabling-svm-amd-ryzen-2400g/
The solution was to disable in BIOS IOMMU per Users old reply but looks like it was temporarily for one reboot only:
Have you installed the latest BIOS/UEFI and CHIPSET from the manufacturer's driver download page?
Open an Online AMD Service Request (Official AMD SUPPORT) and see what they recommend from here: https://www.amd.com/en/support/contact-email-form
I also suggest you open a Support ticket with your laptop.
