Game crashes when clicking the window

Here's what I've tried in order to fix the issue: - I've tried all different window modes (Fullscreen, borderless and bordered window) and I've tried 1920 x 1080 resolution, I've also tried with frameskip on and off. - I've unloaded all my mods and reset all my keybinds....

Server maxbuffs disreprancy?

so I'm trying to make modpack pseudo-server (me hosting a game and leaving it on) but after creating the world when I first try to enter it in multiplayer I get this message and afterwards the world seems to not have the mods listed in the second image (they all seem to be clientside) if I re-validate tmodloader it works fine but it is annoying having to do that every time I make a world

Malicious ip warnings

I know that a majority of the time it could be bots probing open ports when hosting multiplayer, but why do malicious ips flag even when in singleplayer. My ISP picks up traffic regardless if im in single or multiplayer. I would assume that this shouldnt even be happening at all if terraria/tmodloader runs on a private ip when doing an invite only multiplayer world, is this a unfixable thing or is there a solution?

Missing resource

Earlier I was messing with custom menu screens and tried using the Calamitymod public's code, replacing the texture paths with my own. This crash message would pop up, but even after deleting all files relating to calamity the crash message would still show up
