1.18.2 Modded Minecraft Joining Server Error "malformed input around byte 97"

[JustAxtro]

So basically I have this problem with joining my server. The whole thing says "Internal Exception: io.netty.handler.codec.DecoderException: io.netty.handler.codec.EncoderException: java.io.UTFDataFormatException: malformed input around byte 97".
Ive got the client log here and the console from the server. My friend also has this problem when joining my lan world.

I dont have debug log

[Luis_ST]

if you playing on CurseForge you need to enable the debug log in the settings

Alr so here we've got the debug log sorry for taking so long btw. I couldnt paste the debug.log stuff into pastebin so I have the file on mega.io.

I made a new server on my pc instead bc the other one was on a free online hoster but I still got the same problem. 
Debug log was too big so download it though mega instead.

like this? 
REM Forge requires a configured set of both JVM and program arguments.
REM Add custom JVM arguments to the user_jvm_args.txt
REM Add custom program arguments {such as nogui} to this file in the next line before the %* or
REM  pass them to this script directly
java @user_jvm_args.txt @libraries/net/minecraftforge/forge/1.18.2-40.1.0/win_args.txt %* -Dforge.logging.mojang.level=debug -nogui 
pause

I found a debug log without adding the command thing but idk if its the right thing.

I didnt get it to work before because it seems like I had accidentally added a space.

So heres what the user_jvm_args.txt looks like!

I just start my server with double clicking the "run.bat". Inside it it says this.
REM Forge requires a configured set of both JVM and program arguments.
REM Add custom JVM arguments to the user_jvm_args.txt
REM Add custom program arguments {such as nogui} to this file in the next line before the %* or

pause.
Its pretty normal I think right?

[JustAxtro]

Ye well heres the latest debug.log from the server.

[JustAxtro]

Its nothing more you can do then? If you cant find something, thanks for the help so far!

[JustAxtro]
