seo – How long will it take to validate a fix to a “500 Server Error” in Google Search Console?

I opened site (made with Wix) on the 25th August, and submitted sitemap in Google Search console. Then I got the Server error (5xx) in coverage reporting:
google search console Server error

on the 29th August, my website has no other server errors, perhaps the error in side of Wix, I guess.
I started validation in search console, but yet validation status is ‘started’.

My site has not so many pages, about 100 pages.
How many days it will take to validate this issue?
