Search console question

I have 72 urls throwing 5xx errors in my search console (these are all outdated and since deleted pages from my wordpress site - the ones that come with theme by default so were not needed)

According to the console the errors appeared a couple of weeks ago. Looking deeper, the actual pages were crawled late july and early august. My question is, do I have to take any action to get rid of these errors? Or should I just wait for it to resolve on its own? And how long should I expect for it to resolve?

I submitted a validation request on the 19th sept but doesn't seem to have done anything.

Thank you
