Hello, I have a problem. Namely, I don't see any skin, neither in myself nor in others (they all have skins and me). In the launcher, I have a skin loading bar that lasts forever. On the namemc.pl website I have a skin that I have in the launcher. And I know, if other people can see the skin, what's going on? The point is, I can't see their skin or mine. I deleted the .minecraft folder a couple of times and it helped a few times and now it doesn't help anymore. It also gets annoying, because for example from other Minecraft clients (for example Badlion, Lunar Client. No, this is not an advertisement)
I have no skin on non-premium and premium servers. I also don't have it on the one-man mode. I've had minecraft premium for a good 4 years, but I don't know exactly. I read about it on various forums and others have a similar problem, but they see the skin on premium servers with the right plugin and on single player mode.
I feel uncomfortable, because I record for a YouTube channel and it slowly annoys that when my viewers do not see ALL the skins, not one, and when my friend asks if I see his skin, I am a bit ashamed to tell him about it. I don't know if something is wrong with my computer or if I have a bad version or a bugged version of Minecraft. I will add that Minecraft was purchased from the official website.
When I want to see if I have a skin on minecraft.net, the page won't load (the rest is loading). Hope you can fix this error. Greetings.

ps. my nickname is: xEzoF
I will provide an SS with the evidence in the appendix.
