I've been getting this crash over and over again that says "The game crashed whilst initializing game
Error: java.lang.RuntimeException: Could not execute entrypoint stage 'main' due to errors, provided by 'betterfortresses'!" I have no idea on what to do since i've been able to launch before with very little problems. Now instead of just 1 crash then being able to launch after with no problem at all, I have tried to launch 47 times and still this error pops up.

Please share the entire latest.log. It's likely that you're using the wrong version of the mod, e.g. trying to load the Forge version on Fabric or vice versa. It's also possible you're using the wrong MC version. Keep in mind my mods are not available on 1.20.2 and 1.20.3.

Yes, recreate the issue and then it should generate a crashlog. It should also generate a log file called latest.log. Being able to view both of those would help me find the issue.
