My first thought is that this would probably work if it weren’t a multiselect. It being a multiselect means that $value will be outputting an array of users. You’ll need to stick a foreach loop in there to confirm, something like:

<div class="module_col">

		<h3><?php the_sub_field('module_title'); ?></h3>

		<?php
		// Get List of students to check for eligibility
		$students_list = get_sub_field('student_availability' );

		// Set the default state to false, to be changed later
		$student_authorised = false;

		// Loop through students_list to check if user is allowed access
		foreach( $students_list as $student ) :

			// If user is in the list, set student_authorised to true and break out of loop
			//(no need to loop through everybody if they're the first user)
			if( in_array( $student_username, $student['nickname'] ) )
				$student_authorised = true;
				break;

		endforeach;

		// If student is in the list, show download link
		if ( $student_authorised ) : ?>
		

			<a href="<?php the_sub_field('module_download'); ?>">
				<button class="download_btn">
					<span><i class="fa fa-cloud-download"></i>Download Module</span>
				</button>
			</a>
		

		<?php 
		// if student not in list, show authentication error
		else : echo 'Not logged in'; endif; ?>

	</div>
