+
+As a last resort to resolve your issue, please try to clear your `npx` cache, as it could hold a cached version of `create-medusa-app` with errors.
+
+<Tabs groupId="operating-systems" queryString="os">
+<TabItem value="unix" label="MacOS and Linux" default>
+
+Run the following command:
+
+```bash
+rm -rf "$(npm config get cache)/_npx"
+```
+
+Try running the `create-medusa-app` command again.
+
+</TabItem>
+<TabItem value="windows" label="Windows">
+
+First, find the cache directory with the following command:
+
+```bash
+npm config get cache
+```
+
+The npx cache should be in the directory `<NPM_CACHE>/_npx`, where `<NPM_CACHE>` is the cache directory returned by the previous command. Delete that directory and try running the `create-medusa-app` command again.
+
+</TabItem>
