Do you have GradleStart as the main class in the run configurations?

Don't PM me with questions. They will be ignored! Make a thread on the appropriate board for support.

 

1.12 -> 1.13 primer by williewillus.

 

1.7.10 and older versions of Minecraft are no longer supported due to it's age! Update to the latest version for support.

I used to, when I had it on the main class it said in the console:

 

"Error: Could not find or load main class GradleStart"

 

This is what I currently have set to my run condigurations:

 

net.minecraft.launchwrapper.Launch

 

But it gave me the error on the main post of this topic.

      Cannot Launch Forge EXCEPTION_ACCESS_VIOLATION Launcher Exit Code 1

      By defectsnow · Posted

      (i originally submitted this report to CurseForge but since we localized the issue to the modloader they pointed us here)  I am the partner of the user, GalaxyReach, assisting them as they are not as tech savvy. We have spent days troubleshooting a very weird issue that none of our other friends have with a certain modloader.  On a curse-forge launched instance of the Minecraft Launcher, clicking "play" throws an error code 1: crash log says EXCEPTION_ACCESS_VIOLATION. This exception happens in a blank, no-mods test pack as well as manually installing Forge. This issue also happens on NeoForge. We tried All of the steps withing this guide: https://support.curseforge.com/en/support/solutions/articles/9000218027-issues-related-to-the-forge-modloader namely: reinstalling the modpack reinstalling minecraft & curseforge deleting curseforge appdata updating the drivers updating the firewall the computer has been restarted several times we have tried running it on different networks manually installing & selecting java manually installing forge I don't think it is a specs/hardware issue, its a pretty good laptop (HP Omen), 16GB RAM & a 3060. It runs windows 11. Further, launching minecraft like normal through the Microsoft Store runs the game just fine. It is solely with trying to use a modded launch with Forge & NeoForge. I also tried different versions of Forge, though the specific instance I am trying to get running is 47.3.0 Is there anything else we can do here or does Forge just truly not work on this laptop?   Thank you MINECRAFT LAUNCHER GAME OUTPUT LOG 10:07:33.755 launcher main Version does not support log configuration, will assume one plaintext entry per line 10:07:36.419 game 2024-08-31 10:07:36,408 main WARN Advanced terminal features are not available in this environment 10:07:36.586 game [10:07:36] [main/INFO] [cp.mo.mo.Launcher/MODLAUNCHER]: ModLauncher running: args [--username, GalaxyReach, --version, forge-47.3.0, --gameDir, C:\Users\Micha\curseforge\minecraft\Instances\Liminal Server, --assetsDir, C:\Users\Micha\curseforge\minecraft\Install\assets, --assetIndex, 5, --uuid, 7f099235327e4206afdfbc22c7712328, --accessToken, ????????, --clientId, OWEyZTE3Y2MtOTZiOC00MWMwLWFkZjYtNmY2MDU2NmIxNDAz, --xuid, 2535442900827884, --userType, msa, --versionType, release, --width, 854, --height, 480, --quickPlayPath, C:\Users\Micha\curseforge\minecraft\Install\quickPlay\java\1725124053749.json, --launchTarget, forgeclient, --fml.forgeVersion, 47.3.0, --fml.mcVersion, 1.20.1, --fml.forgeGroup, net.minecraftforge, --fml.mcpVersion, 20230612.114412] 10:07:36.593 game [10:07:36] [main/INFO] [cp.mo.mo.Launcher/MODLAUNCHER]: ModLauncher 10.0.9+10.0.9+main.dcd20f30 starting: java version 17.0.11 by Oracle Corporation; OS Windows 11 arch amd64 version 10.0 10:07:37.363 game [10:07:37] [main/INFO] [ne.mi.fm.lo.ImmediateWindowHandler/]: Loading ImmediateWindowProvider fmlearlywindow 10:07:37.452 game [10:07:37] [main/INFO] [EARLYDISPLAY/]: Trying GL version 4.6 10:07:37.503 game # 10:07:37.503 game # A fatal error has been detected by the Java Runtime Environment: 10:07:37.503 game # 10:07:37.503 game # EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x00007ff8a76f59f0, pid=13980, tid=12732 10:07:37.503 game # 10:07:37.503 game # JRE version: Java(TM) SE Runtime Environment (17.0.11+7) (build 17.0.11+7-LTS-207) 10:07:37.503 game # Java VM: Java HotSpot(TM) 64-Bit Server VM (17.0.11+7-LTS-207, mixed mode, sharing, tiered, compressed oops, compressed class ptrs, g1 gc, windows-amd64) 10:07:37.503 game # Problematic frame: 10:07:37.506 game # C [atio6axx.dll+0x1759f0] 10:07:37.507 game # 10:07:37.507 game # No core dump will be written.
