errore TeXstudio

Buonasera (o forse meglio buongiorno)
Sto combattendo da ore con un problema con TeXstudio.
Fino a poco tempo fa lo usavo senza problemi su windows 10 con la distribuzione MiKTeX, ma decido non so bene perchè di cambiare e installare TeXLive2020. Ultimata l’installazione di questo e disinstallato MiKTeX, ho provato a compilare gli stessi documenti fino ad allora funzionati con TeXstudio ma appare il messaggio di errore “Errore: Impossibile lanciare il comando: Compila e visualizza” 😕
Ho rimosso manualmente tutte le cartelle che riguardavano MiKTex, ho seguito anche i consigli trovati su internet (per esempio questo: https://guitex.org/home/en/forum/5-tex-e-latex/98212-impostazioni-texstudio-per-accoppiarlo-con-texlive), ma niente da fare, il problema persiste.

Ho provato a compilare (senza successo) un file molto semplice che riporto di seguito
\documentclass[a4paper]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[italian]{babel}
\begin{document}
Ecco il mio primo documento con \LaTeX.
\end{document}

tale file compila senza problemi su TeXwork, ma non mi trovo con questo editor….

cliccando su “controlla installazione latex” da texstudio, compare la seguente risposta (per me incomprensibile):
