Son and i play java Minecraft and we both get exact same java crash with EXCEPTION_ACCESS_VIOLATION
Example at https://paste.ubuntu.com/p/pTqdDhjMb6/
Have checked drivers are updated, gone back a version (in case the newest release is buggy), adjusted in game memory allocation.
The most interesting finding i came across (though i don't know exactly what it means) is that when i manually put in opengl32.dll into c:\Program Files (x86)\Minecraft Launcher\runtime\jre-x64\bin, the crashes stop. This of course leads me to suspect the video card. Also, i tried some alternate memory and did not receive any crashes. I did get some BSoD later so not sure if the memory was incompatible (was not listed in QVL).

I have not downloaded Java as the MC msi launcher will download Java into the MC folder with Program Files. I can successfully run (no crashes) the game on a decent Dell laptop in this same method of not downloading java separate from the game.

To trouble shoot hardware, i have swapped video cards and RAM with son's PC but not changes. Could issue be incompatibility with Ram/MB/Graphics card/Drivers?
Should have some new RAM in today to check that. But what are the odds that i could have bought two sets of defunct hardware?
I have a simple Dell laptop that is running Minecraft

I'm not one to get angry at machines but i am beginning to suspect that I have a defective motherboard .
I updated bios settings on son's PC to utilize onboard graphics instead of the 2080 Super (i plugged in one monitor to the onboard graphics port on motherboard and disconnected all cables to the 2080 Super). After reboot, all i got was a severely garbled image with only one color: green. My whole intention was to rule out any 2080 graphics card issue by using onboard graphics only. Looks like that is impossible.

So changing UAC to completely disabled (and in admin) does seem to work (but only as work around). Should not have to set this as MC is working without any issue on laptop with it fully enabled.
