When I try to open my modded forge.jar for a server and nothing happens. No window or anything opens. I got this message when trying to agree to the eula ,however, and I don't know what to do with it.

A problem occurred running the Server launcher.java.lang.reflect.InvocationTargetException

        ... 6 more

Any ideas on what to do?

      Struggling to decipher a crash report I'm getting in a custom modpack I'm tinkering with. The crash happens on startup, but weirdly, only some of the time. It seems to be related to Steves Carts, but weirdly it only started happening recently, and I can't identify if another mod is conflicting, or why it is only happening some of the time:   java.lang.NullPointerException: Cannot invoke "net.minecraft.world.entity.player.Player.m_20202_()" because "player" is null at vswe.stevescarts.events.OverlayEventHandler.onRenderTick(OverlayEventHandler.java:24) ~[stevescarts-1.20.1-1.1.14.jar%23527!/:1.20.1-1.1.14] {re:classloading} at net.minecraftforge.eventbus.EventBus.doCastFilter(EventBus.java:260) ~[eventbus-6.0.5.jar%23127!/:?] {} at net.minecraftforge.eventbus.EventBus.lambda$addListener$11(EventBus.java:252) ~[eventbus-6.0.5.jar%23127!/:?] {} at net.minecraftforge.eventbus.EventBus.post(EventBus.java:315) ~[eventbus-6.0.5.jar%23127!/:?] {} at net.minecraftforge.eventbus.EventBus.post(EventBus.java:296) ~[eventbus-6.0.5.jar%23127!/:?] {} at net.minecraftforge.event.ForgeEventFactory.onRenderTickEnd(ForgeEventFactory.java:919) ~[forge-1.20.1-47.1.106-universal.jar%23581!/:?] {re:mixin,re:classloading,pl:mixin:APP:modernfix-forge.mixins.json:perf.potential_spawns_alloc.ForgeEventFactoryMixin,pl:mixin:A} at net.minecraft.client.Minecraft.m_91383_(Minecraft.java:1148) ~[client-1.20.1-20230612.114412-srg.jar%23576!/:?] {re:mixin,pl:accesstransformer:B,xf:fml:xaeroworldmap:xaero_wm_minecraft_runtick,xf:fml:xaeroworldmap:xaero_wm_minecraft_runtick_render_call,xf:fml:xaerominimap:xaero_minecraftclient,xf:fml:xaeroworldmap:xaero_wm_minecraftclient,pl:runtimedistcleaner:A,re:classloading,pl:accesstransformer:B,xf:fml:xaeroworldmap:xaero_wm_minecraft_runtick,xf:fml:xaeroworldmap:xaero_wm_minecraft_runtick_render_call,xf:fml:xaerominimap:xaero_minecraftclient,xf:fml:xaeroworldmap:xaero_wm_minecraftclient,pl:mixin:A,pl:runtimedistcleaner:A} at net.minecraft.client.Minecraft.m_91374_(Minecraft.java:718) ~[client-1.20.1-20230612.114412-srg.jar%23576!/:?] {re:mixin,pl:accesstransformer:B,xf:fml:xaeroworldmap:xaero_wm_minecraft_runtick,xf:fml:xaeroworldmap:xaero_wm_minecraft_runtick_render_call,xf:fml:xaerominimap:xaero_minecraftclient,xf:fml:xaeroworldmap:xaero_wm_minecraftclient,pl:runtimedistcleaner:A,re:classloading,pl:accesstransformer:B,xf:fml:xaeroworldmap:xaero_wm_minecraft_runtick,xf:fml:xaeroworldmap:xaero_wm_minecraft_runtick_render_call,xf:fml:xaerominimap:xaero_minecraftclient,xf:fml:xaeroworldmap:xaero_wm_minecraftclient,pl:mixin:A,pl:runtimedistcleaner:A} at net.minecraft.client.main.Main.main(Main.java:218) ~[minecraft-1.20.1-client.jar:?] {re:mixin,pl:runtimedistcleaner:A,re:classloading,pl:mixin:APP:flywheel.mixins.json:ClientMainMixin,pl:mixin:A,pl:runtimedistcleaner:A}     Including some extra info in case any of it is relevant^.
