What should I do?
Time to switch to another Connection method.
You might need a different emulator too.
AMD64 is CPU's Architecture, which has nothing to do with your CPU manufacturer/vendor, if you're using 32-bit system, it will display as i386 even if your CPU isn't Intel 80386 and if you're using 64-bit system, it will display is AMD64 even if you're not using a CPU from AMD.
Note that it will show AMD64 for 64-bit architectures extending the Intel x86 architecture mostly. I think Intel Itanium based architectures may show something else, but these are server class CPUs that most people wouldn't be running App Inventor with.
For Apple Silicon and other ARM-based 64-bit architectures it will show arm64 instead.
