FastifyError: Unsupported Media Type: application/x-www-form-urlencoded

Bug Report

Current behavior

After upgrading the fastify adapter to the latest version (7.4.2) it stopped working with POST requests, it simply throws the following error: “Unsupported Media Type: application/x-www-form-urlencoded +54073ms | FastifyError: Unsupported Media Type: application/x-www-form-urlencoded” I’m also using the following plugins:

"fastify-compress": "^3.3.0",
"fastify-cookie": "^4.0.2",
"fastify-multipart": "^2.0.3",
"fastify-rate-limit": "^4.0.2",
"fastify-swagger": "^3.3.0",

Input Code

Simply create a new project, use the latest adapter, create a post handler and the error surges

Expected behavior

It should parse as previously, right now if complaints about formbody plugin but if i add the plugin it also throws error saying its already registered. Now the error is internal and out of control in my side
