Emulated/Virtualized environment

• Operating system: my DIY kernel(TYDQ System,which source code is on githubUEFIPascalOS)
• OS/kernel version: 0.0.1
• Architecture: aarch64(arm64)

Description of problem

Shows Synchronous Exception at 0x00000000E46CCEAC and the program halts.

Steps to reproduce

1.Download the UEFIPascalOS on github. 2.run the bash buildaarch64.sh to build the kernel iso. 3.Go through the installer guide and enter the kernel. 4.Enter the account's name and password and press enter,now you can got an error that shows Synchronous Exception at 0x00000000E46CCEAC

Additional information

(no logs,stack traces was shown for the error because logs and stack traces are not exists.) screenshots: If I create two accounts,it will halt on sentence "Welcome to TYDQ System!" and give me Synchronous Exception at other numbers. If I change the memory in virt-machine,the Synchronous Exception showing number will be changed.
