I have a problem, which is that this mod crashes my game at the launch stage. The reason for this is unknown to me. I even deleted everything except M4A1 2019, and the game crashes exactly. Please tell me how to fix this?

If you could post the crashlog, that would help diagnose the reason for the crash.
If you dont know where to find your crashlog, open File Explorer, type %localappdata%, then select Payday 2, open crash.txt
If I had to guess from crashing before opening the titlescreen, the problem seems to be missing some of the required mods (Beardlib/SuperBLT/Weaponlib).
But I cant know for certain until I see the crashlog.

I wanted to download the update with the beardlib updater and beardlib removed this mod.
Do you know why that happens????

That was caused by a mod ID goof on my part.
The 1.02 update should have fixed my goof with the mod ID for Beardlib auto updates.
(Edit): For some reason, Beardlib auto updates mysteriously stopped happening for me (probably one of Luffy's beardlib updates?). If beardlib auto updates worked as normal, I probably would have caught it.
tried to use this mod recently and as Taske_Akai said, crashing on startup
i have weaponlib installed, haven't tried to uninstall other mods but im sure something is just fucked up in the code, but i wouldn'tve known ¯_(ツ)_/¯
(removed some parts to shorten the crashlog)

Hmm, did you uninstall the MW2019 M4A1 custom weapon, but keep the MW2019 M4 Extras for some reason?
Because, if I had to guess, the code is trying to add the various Weapon Painter blueprints to a weapon that is not installed.
(The mod itself adds stuff only to the MW2019 M4A1, not to the vanilla M4A1.
So idk why you would install this, but not the custom weapon it's meant to be used on.)
@RJC9000 guess im pretty stupid lol ty for clearing it up
