There is no error in what you provided. Please provide the full crash report. Subsequently, if it is an issue with Aternos, please contact wherever they provide support.

You need to post the logs/debug.log so we can see the full error. But from the little you show, it looks like one of your mods has broken networking code. Usually the only way to find it is to experiment with removing mods until the problem goes away. (Backup your world before removing mods).

I can appreciate the conundrum this is creating for Forge and the need to make a decision. However; I believe another aspect that needs serious consideration and focus is the balancing of LTS to serve the needs of the 'large mod' devs and the modded community QOL vs the eternal chase of the newest shiny version number. If "LTS" is going to start changing even faster than it used to and end up on the same Major version as Latest then "LTS" will no longer have any useful meaning and should just be called something else so as to not be mocking everyone. I have known several mod devs over the last decade who finally gave up modding even though they loved it because of the constant version grind. They were working on large mods that had great potential for even more development but it felt to the devs like they were spending most of their time updating their mods for the next version instead of being able to work on the features and improving the infrastructure. Sure, updating simple mods as well as essentially complete mods may not be too bad most of the time, except for when more "game-breaking" changes are made by Mojang which affect their mod. But even then it becomes a ridiculous maintenance chase which is not at all conducive to the development of new and improved mods. One aspect of Minecraft modding that has singularly contributed so very much to the modded experience and development are the `Mod Islands` that we are all familiar with. Examples being; beta 1.7.3, 1.7.10, and 1.12.2. Of which I believe 1.18.2 could be a great choice for the next one for various reasons. Modding was able to continue and build up on these levels permitting a large and varied selection of mods and experiences for players as well as time for developers to work on large mod projects which are amazing. These are Modded Ecosystem versions of Minecraft. I hate asking anything that would make more difficulty for your team, but I sincerely believe that another LTS level, perhaps VLTS (Very Long Term Support) or ELTS (Ecosystem Long Term Support), that could be attached to a selected final Major version which has certain qualities, would contribute an incredible amount to the Minecraft Modded community, both for the mod devs as well as the community members looking for a stable/large & varied mod ecosystem that can offer them more than just the handful of new baubles that a new rolling and buggy mc version will give them. I'd argue that the people Most concerned with always playing the bleeding edge version of mc are not the only ones who the entire modding system and community should be bent to serve at all costs. Doing so at the expense of what I spoke about in the last paragraphs would do the entire community a great disservice and knee-cap the best possible mod development. Please consider VLTS/ELTS, or at the very least keeping LTS as the final version of the prior Major version for some sane degree of mod community and dev stability. This will have benefits far outweighing trying to maintain some past rules technicalities at the expense of the entire purpose of the project and community. Thank you for all you have done over the years and are planning to continue doing. We all owe you a great debt of gratitude. P.S. Adding ELTS could be considered a mod community investment project; creation of a Stable Nursery for new mod and mod ecosystem development. This would be an incredibly attractive place for devs to be able to catch their breath and just focus on pure mod development, and for players to just build and enjoy collections of mods with increasing options for more mods and synergies without the dark pattern of feeling like they have to jump to the newest "version" of mc pulling at them as much, which makes them lose mods again and again which actually reduces the draw of modded vs vanilla. tbh; The modding community shouldn't be run into the ground by the marketing needs of Mojang and Microsoft. They have their legitimate concerns and things they need to do, but those are not the same thing as what best serves the modding community.
