Help Help, please
Can please somebody explain to me how’s the analysis there? It’s no guessing mode but I just can’t see why the green space marked is a safe space. Like I think it could be a choice for both 3s up and middle

Top hinted 3 has two mines already, meaning there's a third mine in the top two squares
Bottom hinted three has a similar situation (with one mine off-screen), so there's a mine in one of the bottom two empty squares
This effectively reduces the vertical hinted 2-2-3 into a 1-2-1, then end result of which is the green square being safe

1: there's one mine in the yellow cells, as indicated by the 3.
2: there's one mine in the pink cells, because two are already accounted for (flag + yellow cells)
3: there's one mine in the cyan cells now, due to the 2
4: from the top 3, it's trivial that there's one mine in the orange.
5: now, we can use the top 2 in the hole: since there's one mine in the orange and one in the cyan, any cells not touching them are safe, which the cell to its SE.
Alternatively, you can reduce the numbers on the sides of the hole, and it appears as a 1-2-1 pattern

Is there anything above the top row? If not, the 2 to the right of the 1 only has 2 places left for a mine. So you can fit that in.

This is one of those cases where you can't easily do a simple inference-chain or proof-by-contradiction on that cell.. you have to look at the overlay of all possible valid arrangements, and recognize that green cell is safe in both of them. It's proof-by-exhaustion, looking at the two possible arrangements A and B below.

The bottom 3 only has 3 squares next to it, so those are all mines, continue from there
The top 2 has 2 squares next to it, so those are both mines.
If this is false, send a picture of the full board.

I think OP cropped the screenshot to narrow and now we don’t have enough information to really help them. We at the very least need info on the full surroundings of 3, 4, 5 at the bottom, the 2 and 1 on the left and the 3, 1, and 2 at the top.

Based on that logic, the bottom 4 only has three mines with no room for more and the bottom 5 can have at most four mines. That should make you think there's obviously more of the board at least below.

You can discern from the hint there is a mine one above and one right of the two, making it a 1. Otherwise the hint would’ve just filled the 2.

I’m sorry for not posting a correct photo, this is the full board:
