Context
I have recently tried to launch 2 of the same minecraft versions of 1.12.2. What usually happends is that I successfully launch 2 minecrafts with no errors but this time it was different. I did a lot of research into this issue and i was lead to belive that the problem was that I had not had enough space on my Disk C: which at the time i had over 27GB. i have managed to free up to 92GB and then i tried launching 2 1.12.2 minecrafts 1 after the other and I still had the same issue. i then checked out a few tickets here and found that this issue has been appearing for 10 Days and all the tickets have set as "invalid" due to how people structure their report and due to lack of detail.
Recreate

To recreate this issue i have found that really any version starting down from 1.18.2 has this issue.
1. Open the game launcher and select any version from 1.18.2 downwards (i will be using 1.18.2 release as an example)
2. launch the game normally and wait for minecraft to load up into the game menu
3. now open the launcher again and launch the exact same version as before (1.18.2)
4. you will then get this error.

Further detail
I have asked around for people to try these steps and they also had the EXACT same error so that further lead me to believe that i am not the only one affected by this issue.
It is possible to launch 2 of the same version minecrafts as long as they different directories. so if you were to have .minecraft and .minecraft2 folders duplicated then you are going to be able to launch the same versions simultaneously. You can also launch multiple minecrafts at the same time as long as they are different versions, for example 1.12.2 and 1.18.2 and 1.17.1.

Possible problem
I am not an expert in technical aspects of minecraft, but i think that whenever this "3.2.2-natives-windows.jar" is created it has its own fingerprint wich is the game version and whenever the launcher tires to launch another of the same version there are 2 of the same fingerprints which cause the launch to fail because the stop for the finger print is used up.

Justification
This error ONLY happends whenever launching the second minecraft, the first one launches without error. This is not a operating system error and this happends on all of my friends' computers.

I hope the moderation team will bring this forward to the developers and this issue will be solved. This problem IS valid because there are many people with this same issue. If you can't take my word then please host a survery for people to follow these steps and ask them if they get an error.
