Minecraft Java doesn't load when "play offline" pressed when not on Wi-Fi

Thanks for the image. Let's see when you get home.

Yeah, I can play online just fine. I work 3rd shift though, and on slow nights, I play a lot of Minecraft. It makes me mad that I can't, and I was JUST able to, since I've never changed that before. Even if having multiple accounts like you say is an issue, that would've started right away in late November, not at the end of February. Which makes me think it was a Microsoft update that changed that.

That link you gave me shows this computer (laptop) as my only device. I haven't even logged into Minecraft on my old laptop since I got this one.

So, I opened Microsoft Store (something I have never ever opened, because, I wouldn't need to), and offline permissions was set to off. When I tried to toggle it, it gave me an error log saying that this was the 3rd time I've changed it in 365 days. I have NEVER opened that app before at all, and I just bought this computer on Black Friday besides. So, who's messing with my settings from Microsoft? I was able to play Minecraft offline until 2 weeks ago. No one has access to my computer besides my, in my in-person life.

They should be using the same account, as I've only got the one Microsoft account. I don't use either app on my PC, only the Minecraft launcher itself. I'll check all those settings when I get home and back onto Wi-Fi.

In the meantime, this is the message I get:

Thanks for trying. That must be the reason why you cannot play the game offline. Just to be sure, you're able to play the game just fine when you're online, right?

Try to check your account through https://account.microsoft.com > Devices if you can see multiple devices you do not use. Remove those devices that you no longer use or own.
