Try disabling Placebo's faster recipes

Use a more recent version of Forge, toss out whatever tutorial you're following (Never set _JAVA_OPTIONS, throw out any tutorial that tells you to do so), and install a JDK. I recommend getting java from https://adoptopenjdk.net, you'll need Java 8 Hotspot for x64

Are you sure that's assets/moreslabsmod and not a folder called assets.moreslabsmod

There's definitely drama between small groups in Forge and Fabric, some of Fabric's fans have been anti-Forge since before Fabric was a thing and now they have a non-Forge loader to hide behind. I haven't personally seen their Forge counterparts, but Fabric's Discord moderators have assured me they exist.

This happens when you have somehow set IE to open jar files. Make sure you have Java installed, run JarFix once and try the installer again.

This issue is caused by poorly written code in vanilla that doesn't show until the number of advancements gets ballooned by mods. Current versions of Forge have fixed this issue, it shouldn't happen again unless you disable the fix via config.

Please don't Necro old threads, if you have an issue make your own.

Fabric is INCREDIBLY lightweight, they provide the loader and a minimal API, this allows them to be quite agile but by the same token modders must make heavy use of Mixins (coremods) to write their own hooks into the Minecraft code, which is typically not good for stability if done poorly or when many are combined in a single modpack. Forge on the other hand is a bit of a fat bastard but comes with a ton of utilities and hooks set up with the goal of providing everything a modder needs so they never need to directly modifiy the Minecraft code, essentially Forge tries to do the ugly so modders never have to.

Don't use MCreator, learn Java and make your mod properly

The client shouldn't be opening a command line window. What launcher are you using? How did you install Forge? What Minecraft version are you using?

This is a client or a server?

Deferred Registers are there to placate people who felt they needed to statically initialize crap. They are just a wrapper around the Registry Event system.

Not really helpful unless you're providing extra info

I can only recommend you remove Optifine. Outside of their own fanbase they are actually rather notorious for issues stemming from how they advertise themselves vs what they actually accomplish, and their closed-source stance.

That doesn't show a crash. When you say "crash" is it just freezing or is it booting you back to the launcher and saying it crashed?

Please keep this forum in English, please don't necro old threads, 1.12.2 and below are no longer supported, please update to a modern version of Minecraft to receive support.
