Ok so, last month I was hitting all of my shots, on soldier btw, and then after a week after I started missing absolutely everything, I tried playing mge, dm, training maps but they won't "help" me anymore, and it just keeps on going like this, and by that I mean, for a short amount of time I am hitting my shots and then for some time I start missing everything, and it's really annoying, are there any tips for this kind of problem? Ty in advance.
P.S: I am not always playing soldier, I tried playing other classes for a while (scout, demo) but it's just not working out.

Worked, ty

Whenever I start tf2, sometimes it makes it random, the background of my hud is black and i cant do anything, and if i press on a button on the menu the specified thing is on the background but i can't see it.

Verifying game cache worked, ty very much :)

I will try verifying game cache, and I have tried removing my hud and it still does it.

I don't get an error message, it just freezes and then I have to open task manager to end the process because it says that TF2 is not responding at that time.

After the Junlge Inferno update my TF2 keeps crashing a few seconds after i join jump servers and when i'm offline on tr maps, how can i make it stop?
P.S: I think it's because my hud because i modified it a bit (the chat being on bettom left instead of top left and different color damage numbers) and i'm using m0rehud black.
