When I start a custom jar file, I get the following error.

2023-01-15 01:02:26,846 main ERROR Error processing element Queue ([Appenders: null]): CLASS_NOT_FOUND 2023-01-15 01:02:26,852 main ERROR Unable to locate appender "ServerGuiConsole" for logger config "root" [01:02:27] [main/ERROR]: Unable to launch java.lang.reflect.InvocationTargetException: null at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ~[?:1.8.0_51] at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) ~[?:1.8.0_51] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) ~[?:1.8.0_51] at java.lang.reflect.Method.invoke(Method.java:497) ~[?:1.8.0_51] at net.minecraft.launchwrapper.Launch.launch(Launch.java:135) [launchwrapper-1.12.jar:?] at net.minecraft.launchwrapper.Launch.main(Launch.java:28) [launchwrapper-1.12.jar:?] Caused by: java.lang.NullPointerException at java.util.StringTokenizer.<init>(StringTokenizer.java:199) ~[?:1.8.0_51] at java.util.StringTokenizer.<init>(StringTokenizer.java:221) ~[?:1.8.0_51] at joptsimple.ArgumentAcceptingOptionSpec.addArguments(ArgumentAcceptingOptionSpec.java:263) ~[ArgumentAcceptingOptionSpec.class:?] at joptsimple.RequiredArgumentOptionSpec.detectOptionArgument(RequiredArgumentOptionSpec.java:50) ~[RequiredArgumentOptionSpec.class:?] at joptsimple.ArgumentAcceptingOptionSpec.handleOption(ArgumentAcceptingOptionSpec.java:257) ~[ArgumentAcceptingOptionSpec.class:?] at joptsimple.OptionParser.handleLongOptionToken(OptionParser.java:513) ~[OptionParser.class:?] at joptsimple.OptionParserState$2.handleArgument(OptionParserState.java:56) ~[OptionParserState$2.class:?] at joptsimple.OptionParser.parse(OptionParser.java:396) ~[OptionParser.class:?] at net.minecraft.client.main.Main.main(SourceFile:79) ~[Main.class:?] ... 6 more

and when I try to start a plain optifine 1.19.2 installation, I get this error

[MCLC]: Failed to start due to TypeError: Cannot read properties of undefined (reading 'url'), closing...

Still have the problem, any ideas?

Mind posting your version json? Also, how did you install optifine?

Please reopen this issue once you send the version json you were using.
