Posts is no longer indexed after getting redirect error

Greeting community, my post suddenly disappeared from google search, only pages and tag/category archives appears. its WordPress site (educationng.com)

RETRACING MY STEPS

These are the three things i did on my site without knowing what actually caused it

1. installed light speed cache

2.? installed 'Email Subscribe pop up' on post pages alone.

3. Got a redirect error for my post page (educationng.com/blog) on my GSC?

WHAT I HAVE DONE SO FAR

1. uninstalled lite speed cache since my web host said they already use lite speed cahce for all their servers

2. uninstalled the EMAIL SUBSCRBE pop up plugin

3. Changed my post page to (educationng.com/articles) since my fix for redirect failed twice on GSC for the initial post page.

4. Place all my Tag archive pages to No-index on my yoast plugin.

NOTE:

1. My site posts use to rank very well on google search before all these.

2. My posts index in GSC but does not appear in search results even when i use site:educationng.com, only pages and archive appear.

3. its been about 2 weeks now no improvements

4. i have no security issues or manual actions on my GSC
