Hi @baashaas

welcome to the arduino-forum.

You posted the compiler-log which gives some information.
This information is not sufficient.

I'm pretty sure that you agree and will follow the way how to solve your problem mimimum 200 minutes faster.
This requires to invest 20 minutes of your precious time to read how to speedup solving your problems.

Directly after registering you got presented informations how to speed up solving your problem.
You should really read it.

This tutorial guides you what kind of additional information you have to post so that somebody can really help you.

You seem to be able to read. Do it ! Read the tutorial

The output you posted shows three things:

Your sketch successfully compiled.

There is an invalid library at the location shows. Might just be an empty folder named "libraries" within the "libraries" folder. This does not indicate an error with your sketch, or that it relates to a library used in your sketch, its only a warning that an invalid library exists within the libraries folder.

The avrdude messages indicate that there is an error communicating with the Arduio UNO. There are several possible causes for this, such as specifying the wrong port under Tools > Port, a driver problem in the operating system, a wrong board selection (such as UNO unstead of UNO R4), an actual hardware problem with the UNO, etc.

@david_2018

etc

can include a bad cable, or a need to reboot your sdsektop machine or fully remove all power from the arduino board for long enough.

In this circumstance, a quick check is to use the blink sketch while you get the uploading problems sorted, so you on,y looking at one issue at a time.
