If problem A itself is very hard then many participants will not even participant in the contest because of fear of loosing rating.
And because of that number of participants is too less than than the number of participants registered for the contest.
And it will affect the overall rating of many users. (Obviously who atleast solved A should have higher ranking than the one who not even solved A , but according to current scheme if user not made any submission that means user is no more participant for that contest.)
Make problem A very easy so that they do atleast one submission for the contest.
What's your thought on this point ?
Thank you.

Indeed. This time A was so much harder. On average I solve problem A in like 4 minutes but this time it took me 15. It really has a big effect on the number of participants. I have never seen a round with only around 5000 participants.

OR They could add a rated/unrated register option like AtCoder.

Friendly advice Never attend contest set up by 74TrAkToR. Because they are always with mathematical problems and observations in them

Not only that, today most people participated in 1st contest and were too tired to participate again, like myself

It also harms the problem ratings.

Read the whole blog

I agree that Problem A should be easier; it also boosts the morale of the participants.

In the last round A was really hard. Anyway, I believe that the rules need to be changed: for those who have opened and read at least one task, they should already be considered as participants, so that there is no temptation to skip the competition.

Usually, div2A and div2B can be bruteforced as problem setters tend to lower the limited for arrays sizes, and every now and then I get stuck and frustrated trying to solve them, so I find myself writing some brute force with some DP if needed for such problems, check out my solution for the last A problem, it's probably bad advice to avoid the intended solution in favor of the dump bruteforce one, but sometimes it can save the day.

Just grind on the problemset man. Eventually you will become good.
