I have this error for many different mods like JEI, YungsBetterDesert... Unable to launch my game 😭, it's with new forge versions.

Please solve the problem 😭

Can you please be more specific with your setup? What is your entire modlist? Your Minecraft version? Forge version? Kotlin for Forge version?

error.txt
Here is a file that contains all the info

Are you able to reproduce this outside of TLauncher?

Here it is with the official launcher:

Can you send the crash error from there?

I have no crash reports

I now don't have the problem anymore, I'm sorry I couldn't give you more details and thanks anyway for your help

Check the .minecraft/logs folder for a file called "latest.log" or "debug.log"

I changed my hard drive recently, without keeping the data from the old one. So I can't see if I had those files. But the error created no crash reports.

I can't really help without a debug.log, the error you sent from TLauncher didn't contain enough information (not to mention it's a pirated launcher)
