How to identify what's wrong with the PGN?

I have been playing the Roblox game Chess! from time to time and have some fun plays I like to remember. Thankfully, the game offers a copy paste PGN that can be downloaded. I was wondering though, there is this one PGN that can't seem to be pasted while a game after it works. I wonder why. 

Here's the PGN that worked.

[White "TheNeoNoble"] [Black "suffixwhen"] [WhiteElo "1158.2039265601986"] [BlackElo "1096.4175075973121"] [Result "1-0"] [Termination "surrender"] [Date "2023.03.24"] [Time "09:57:09"] 1. e4 d5 2. e5 Nb8c6 3. d4 f5 4. Ng1f3 a6 5. Bf1d3 b5 6. O-O Bc8e6 7. Rf1e1 g6 8. Nb1c3 Bf8g7 9. b3 b4 10. Nc3a4 g5 11. Nf3xg5 Be6d7 12. Na4c5 Nc6xe5 13. Nc5e6 Bd7xe6 14. Ng5xe6 Qd8d6 15. Ne6xg7 Ke8f7 16. Ng7xf5 Ne5f3 17. Qd1xf3

But the PGN match before this game does not work. 

[White "suffixwhen"] [Black "TheNeoNoble"] [WhiteElo "1096.4175075973121"] [BlackElo "1158.2039265601986"] [Result "0-1"] [Termination "surrender"] [Date "2023.03.24"] [Time "09:52:31"] 1.

Was wondering if anyone can give any tips on how to troubleshoot this issue? I had a similar issue before that I was able to fix and it was just removing the decimals on the elo rating but this time it seems to be not the case or perhaps it has multiple errors that is the cause? 

I pasted this in another chess website and it works, I wonder what's the case with this website.

Ah, I found a troublshoot way which is to simple paste it in the website that works, then copy paste the PGN that website generates from the same game! Yey

Yeah, only because my laptop can handle it and barely any Steam games due to OS capabilities. Finding that there's a Chess game in Roblox is a fun discovery and I hope Levy or Hikaru gets to try it haha

The road blocks version of chess is harder to understand or read.

bruh just turn the camera perspective over the board (no offense)

This device comes with a broken camera, so that's not happening.

Interesting story
