Most of my posts in search console are showing

URL is on Google, but has issues

I checked Crawl Page more info section and found out the blog post with many images show other error and the image link as shown below:

Important Notes:

• Posts with few images crawled successfully and show "URL is available to Google"

• The same post with many images show "URL is available to Google" without any error when I performed "Page Live Test"

I understood it’s because of the Crawl Budget limit!
So my questions are

• Is "URL is on Google, but has issues" error will affect my ranking on google?
• Should I set images to no index to avoid crawl budget limit
• Although I only have around 500 posts, I would like to know why I am facing crawl budget issue)
