There could be multiple reasons behind it, so please try below options
1. Please edit or create user.ini at root level and paste below code
memory_limit = 2048M
max_execution_time = 1600
max_input_time = 160
post_max_size = 120M
max_input_vars = 2000
file_uploads = 4
max_file_uploads = 20
upload_max_filesize = 750M
2. If still problem does not fix , then edit wp-config.php file and add below code
define( ‘WP_MEMORY_LIMIT’, ‘2048M’ );
3. Sometime this happen due to image size to so please try to compress, you can try tinypng.com to compress images
4. If still you get the issue please check upload folder permission this should be 0755.
Please add your comment if any fix works for you.

]]>wp-content
wp-admin
wp-include
.htaccess
user.ini
wp-config.php
upload folder should be inside wp-content, so go to that and there should be some file permission option either infront of that or on right click.
