It tells you what's wrong in mostly plain english if you look at where the error starts: There's a problem with your resynth modded-plants.toml config file, based on that. Either try removing the mod, or finding out what's wrong with the config file (would likely require contacting the mod author, unless you get lucky and someone else knows that mods config). This is likely the case of the subsequent errors, although if not that mod might just not work right.

Learn basic Java. Syntax (i.e. most lines end with a ; where curly braces go, etc), keywords (if..then, etc), structure (classes, methods, variables/fields), how inheritance works. Choice of IDE is personal, I use eclipse myself, intellij is a popular one. Whatever you choose, get familiar with it. Learn how to launch applications in debug mode with it, so can set breakpoints, which stop code execution at the breakpoint and allow you to inspect the values of variables and fields from that point in code. Honestly, for best results, you will need to start small, and perhaps write some text-based programs to get the basics down. That is what I would advise at least, otherwise you will potentially have questions that are too much basic java to be asked on these forums. *edit: Oh, and don't start at 1.14.4. Start with the latest, otherwise you are going to end up being out of support when the next version comes. *edit 2: google is your friend. "java tutorial", "beginner java programming", "what is a class in java?", just ask google, it probably knows!

My guess is that the version of forge you are using is too new for the version of the mod. Check release dates, and use the last version of forge released at the time that mod was written.

I honestly do not know, I never had problems when I used 1.12, but I am on the current 1.15.2 now. You should just rip off the bandaid and update Topics for old versions like this get closed once a moderator sees them, seeing as they are no longer supported here.

I know the official minecraft forums have a modding section, but I don't really go there so I don't know how good the people there are or what versions are supported.

What if you try playing without your BDCraft resource pack? Are you using the super ultra mega one with the highest resolution? Try it with vanilla, or a smaller res resource pack and see if it still crashes. edit: also, use F3 to make sure it is using your Nvidia card, and not the built in Ryzen graphics.

That log does not appear to be complete, as far as I can see it does not even show the server completing startup nor accepting any client connections.
