Thanks for the bug report. I can see two main problems here:
1. The amdgpu kernel graphics driver is emitting warnings that look like crashes.
2. The rtw_8821ce kernel wifi driver is flooding the system log (this is probably the performance issue).
So I can only suggest trying an older Ubuntu release like 22.04.0 with an older kernel:

So I can only suggest trying an older Ubuntu release like 22.04.0 with an older kernel:
https:/ /old-releases. ubuntu. com/releases/ jammy/ubuntu- 22.04-desktop- amd64.iso
or trying newer kernels from:
https:/ /kernel. ubuntu. com/mainline/ ?C=M;O= D
or disable wifi and use wired networking;
or replace the wifi card in the laptop with an Intel one.
