My games will crash when OBS is open

[QuietNono]

I am writing this post once again, cause no one has taken a look at it and I'm out of ideas..
When I open Minecraft, no matter the original launcher (Vanilla Minecraft), Prism, or Modrinth, the game will crash. But it will only crash if my OBS is open. If it's closed, Minecraft and every other game work smoothly. (I have looked its not a problem of too little memory) I
1. completely reinstalled my driver,
2. I reinstalled OBS and Minecraft,
3. I changed every OBS setting i could find (also reinstalling it again to have it set to "normal"),
4. I have removed every plug-in, changed Minecraft to "Game capture", and "Window capture",
5. I changed my encoder,
6. changed my quality,
7. updated my drivers.
I have also opened a completely new Windows profile in which Minecraft worked when I had it on "Bandwith" (testing), after a week it crashed again, even though I changed nothing. I have already submitted a post in the Minecraft forum, which got cleared cause the people think it has nothing to do with their program (which is understandable if it just crashes when OBS is open). If you need any specifics of my computer, drivers OBS settings ect. please let me know it has been very upsetting to work with this program for the past month, thank you for reading!

Please provide a crash report and the log file from the moment it happened.
What you describe looks more like a hardware issue.

the one i put in is the most common type of crash that I get from minecraft. I'm not good with computers, what does it mean if it's a hardware issue? I have had streams where mc would work for hours without any problems before that's what confuses me the most

That's a crash within Minecraft, not OBS.
For issues on the game you have to contact the game's support.

A hardware issue means something on the computer may be failing. It could be the GPU, the CPU, the motherboard, the memory RAM, etc.
And still we need the OBS log file and crash report (if crashed). Look inside the Help menu. Yes, OBS have an useful Help menu.

The "Access_Violation" 0xc0000005 means that program attempted to access part of the memory that doesn't belongs to it. OS in the PC manages all hardware resources. RAM is one of the resources. For example, application asks OS "Hey, I need 1MB of RAM to store my important data (let's say texture image)" OS responds: "OK, here is the ticket for 1MB block of free RAM, show this ticket to me again if you no longer need your data". The ticket points to area in the RAM where you can store data (from point A to A+1MB). If for whatever reason your application will attempt to access point A+1.01MB then OS will halt your application and will rise "Access_Violation" error. Because all hardware resources is under the management of the OS, and only OS knows which resources are busy by programs and which are free (otherwise you'll get mess of data from different applications). For the right management OS uses special programs named "drivers". Thus, the error you see, can be mistake in the algorithm of the application, OS, driver or it can be malfunction hardware (for example if ticked was damaged during transfers or under a heavy load).

In short, if Display Capture source works OK for your game and "OBS + your game" doesn't results in a crash - use it instead. Because the Game Capture source of OBS uses memory pointers to where game renders its pictures and everything may fail ( example: https://github.com/obsproject/obs-studio/issues/9168 ). Display Capture is less sensitive to the game itself and depends more on the OS itself (of course, don't mess both sources together in one scene).

Capture card and second PC for capture may work better in case you noticed incompatibility in your applications.
