Nodemon dont start the server.js

I recently started using Nodemon. But when I run this command “nodemon server.js”, comes this:

nodemon server.js
[nodemon] 3.1.9
[nodemon] to restart at any time, enter `rs`
[nodemon] watching path(s): *.*
[nodemon] watching extensions: js,mjs,cjs,json
[nodemon] starting `node server.js tailwind.config.js`
[nodemon] clean exit - waiting for changes before restart

The problem is that Nodemon tries to start two files. How can I fix it? I have no nodemon.json file or similar. I installed Nodemon with npm install nodemon
