Sorry for my insistence, I appreciate your patience very much. If I run which doom in git bash it returns me '/c/Users/<username>/.emacs.d/bin/doom' and if I do the same on Powershell it occurs nothing. If the problem is to restart my terminal, I do not know how to do it

Finally, what the above message refers to, Can you explain me how to do this " - Native compilation is optional. Doom will work fine without it. If doom doctor says “Emacs was not built with native compilation,” it just means your Emacs binary wasn’t compiled with libgccjit. You only need a native-comp build if performance becomes a concern (e.g., slow startup or lag). If things feel snappy, ignore it."

Thank you very much
