"Oops! Plutonium ran into a problem and must be closed" - An error with no apparent solution

[Vellok]

I have seen that many have had this error at many times (With small variations and specific games, in my case it happens ONLY with Call of Duty: Black Ops 1) and in the end no one has been able to solve it correctly, many administrators give the same indications (which are a copy and paste sometimes ...), I have tried and I have seen many who have tried each of these solutions they give: Restart the pc (Laptop in my case), update drivers, configure the plutonium exe, reinstall the launcher, reinstall the game, move the game from place, etc, etc, etc. No solution really works and in the end the posts where this error is commented are closed or simply abandoned, so.... As possibly the 50th person to have this error...I ask.... How do I fix it, comrade?

UPDATE: After a while I managed to solve this error, at least for me, I consider this a definitive solution so you can try it.

First of all you need these configuration files

Once you have downloaded the text files you have to place them in the following location: %localappdata%\Plutonium\storage\t5\players

If the “players” folder does not exist, simply create it
