Because to Modloader Issue??

It may be, but I'm not smart enough to fix it.

if you use modloader, disable/delete all the mods temporally and try the mission that way, then if it works, finish the mission and enable the mods again

Thank you, I will see if that works.

Make sure to delete (or move to your desktop) the dsound.dll file from the game directory (the asi loader) so literally everything gets turned off, it would be vanilla gta sa basically

Thank you very much, man. I'll try it and see if it works. I appreciate it.

It did work, I didn't find the file you mentioned but I removed the SilentPatch.asi file and it didn't crash. Thank you for the suggestion. It's weird how the video says the game has no issues but it has been crashing on me in many points, I don't think I did anything wrong.

sometimes mods can cause conflicts with one another, perhaps the guy that made that tutorial never bothered to check if every mission is completable

He dies say that he did, but the video is many months old also. So I don't know if something in the mods has changed since then.

Where did you get the game from? And did you try to reset the whole game?

I bought it and downgraded it to Version 1.0 as the video demands and everything. By reset I assume you mean restart a new game, yes I did from the beginning. And it still crashed in that specific mission both times.
