Czechoslovakia had a rather large prewar Fascist movement known as the National Fascist League, led by former Czechoslovakian Legion officer Radola Gajda. They were followers of a more Italian style Fascism.
Let's assume that this Fascist Czechoslovakia is led by Gajda, let's also assume he comes to power between 1926-1933. We know he was both anti-Polish and anti-German, so we know he's not giving into German demands while also not compromising for Polish support. Its ambiguous whether he'd support Austrian independence or whether that support would have any impact so let's say the Anchluss goes as otl.
The Czechoslovakian Army iotl 1938 was one of, if not the most, advanced in the world in terms of armor. Not to mention a strong air force, imposing land fortifications, and a relatively large and well equipped land army. Radola Gajda was a well known army officer himself and had a good war record during WWI. It's safe to assume that any fascist government will expand its Nation's military, especially one led by a war hero and general, who had very poor opinions of his neighbors Poland and Germany. The ittl Czechoslovakian Armed Forces would be likely larger and probably slightly better equipped. Unfortunately I can only find conflicting iotl stats on the Czech army, so I'd be happy to see if any here as any good ones. What is known is that the Czechs iotl possessed some ~450 modern combat aircraft, 200 fighters and 250 bombers, and around 600 tanks iirc. With the NOF and Gajda in charge the Czech army and air force would be much larger. Let's also assume that the otl defensive fortifications are finished and more extensive by 1938.
Come 1938, Hitler demands the Sudetenland. The Wallies are unwilling to intervene to protect a Fascist Czechoslovakia besides condemning Hitler. Mussolini condemns Germany and offers diplomatic support to Czechoslovakia. Gajda promises that the Sudetenland is Czech and any attempts to alter that will lead to war. Hitler declares war.
I think that the Czechs would hold their defensive positions. The Luftwaffe suffers significant casualties due to AA and the Czechoslovakian air force, they do, however, manage to maintain an advantage in the air. The Wehrmacht is repulsed. By the end of the first month of war Germany has failed to make significant gains. A number of Royalist soldiers in the German Army launch a coup and overthrow Hitler. They sign a peace deal recognizing the Sudetenland as Czech and agree to pay reparations.
