In these screenshots below are mods that I intend to use, some of them are the ones I intended to use, but the screenshots taken from Aternos crashed the server, even though updated versions of them work perfectly with TLauncher. The 1.16.5 Forge version worked with all of the mods before, all I needed to do was have all the mods match. The only glaring issue was it wasn't showing the skin model so I switched from 1.16.5, Forge version 36.2.0 to 1.16.4, Forge version 35.1.37.

(All of the mods activated that I use or plan to use)
(Mods installed in the server) //Yes, I intend to clean up the repeating mods but I don't know which one I should delete//
Earlier, I was removing the copies of the mods in the server since the duplicates were making the server crash, and I can see them in the log files. "Ah, yes. This version of the mod is for 1.16.5, I'll download the one that works with 1.16.4 instead", and tested it in the launcher. Did this for all the mods up until Mowzie's Mobs Mod and other mods that I can identify in the crash log (https://mclo.gs/QjoGxSG). I can't understand the issue this time.
Is this something that can be fixed by just choosing a specific version? Because the crash log makes it difficult to identify which one of these mods are the ones that I should delete or replace.
After this is posted, I'll try to clean up the mess of a mods folder this is, if not a complete redownload of all of them from scrap to see if it works. Thanks to anyone who'll help fix this issue.
