WebAssembly Emscripten on macOS M1

Trying to use the WebAssembly sample project and following this:

The emscripten activation step from 1.39.4.7-mac fails:

➜  emsdk ./emsdk activate latest-fastcomp
Writing .emscripten configuration file to user home directory /Users/dev/
Error: No tool or SDK found by name 'sdk-releases-fastcomp-8bb7b0bbbca74cc58741416cc955011f22ff5ccb-64bit'.

Is this just because I cannot do it from an M1 mac machine?

As far as I know, Tizen studio does not support in M1 machine. So you may face different types of problem as it is not officially supported. You can check with ADB instead of UI.
I have found similar suggestion in this guide:
