That debug.log doesn't match the other log, I don't see the message about an invalid move player packet in this new log

Please provide debug.log using one of the paste sites in my signature. I see a few errors here but none of them are outright claiming responsibility.

This is latest.log so I only have limited info, but I see usefulbackpacks blowing up which appears to shut down the event bus preventing further events being fired. You should be getting an error screen explaining this.

You downloaded which file from what URL?

Please provide your installer log, it will have the same name as the installer but with .log on the end: Installer: forge-{version}-installer.jar Log: forge-{version}-installer.jar.log Note: If you have Windows Explorer set to hide file extensions(as is the default setting), they will look like this: Installer: forge-{version}-installer Log: forge-{version}-installer.jar

Don't extract/unzip mods You appear to be mixing 1.12.2 and 1.14.4 mods, this is not going to work as mods are not typically compatible across MC versions (with the possible exception of bugfix versions) That does not look like a preview version of Optifine and at this time Forge compatibility is a preview feature in 1.14 Optifine

What kind of network are you on? and I ask this referring to both network quality and management (i.e. college wifi or something)

RLCraft is not a mod, it is a modPACK. Can I ask where you got the idea that this method of installation would work for a full modpack?

Don't make duplicate threads It sounds like you're telling Chrome to run the file instead of saving it, this is not what you want.
