What's Wrong?

After I updated claude to 2.1.113 (or higher) when I open it, it just crashes with this error:

Bun v1.3.13 (6db6c97b) Linux x64 (baseline)

CPU lacks AVX support. Please consider upgrading to a newer CPU.

oh no: Bun has crashed. This indicates a bug in Bun, not your code.

What Should Happen?

It should open the claude code in terminal
