On Windows arm64 you return before writing post_event.json. That breaks the existing “post step already executed” guard, so if the action is used multiple times in the same job the post-step will run (and log) repeatedly. Consider still creating a post-step marker (e.g., write post_event.json after ensuring agentDir exists, or use a marker location independent of C:\agent) before returning.

Suggested change
if (process.arch === "arm64") {
if (process.arch === "arm64") {
try {
if (!fs.existsSync(agentDir)) {
fs.mkdirSync(agentDir, { recursive: true });
}
fs.writeFileSync(postEventFile, JSON.stringify({ event: "post" }));
} catch (error) {
console.log(
"warning: failed to write Windows post-step marker:",
(error as any).message || error
);
}
