So I got a very trusting minecraft mod the other day: Optifine 1.12.2 andafter checking various sources, I downloaded the mod with no problem. However, when I changed the resolution diwn to a low level, it was the surface that messed everything up: it said that, in a notification, it automatically adjusted the resolution to match "the app's" resolution. Everything was EXTREMELY enlarged and I couldnt move the cursor anywhere on the screen, so I restarted my laptop, and that's when everything went downhill. Now anytime I turn on the laptop, a BIG cursor arrow appears and the lockscreen is blurry af. When I type in and enter my password (which I CANNOT SEE), it goes to a blue screen with a fuzzy windows logo. The only thing I can do is press the home button and + or - and even then that "resolution change" does NOTHING. I cannot access my laptop anymore and I am terrified that I may lose all of my data on there, and if that happens, every thing that I have worked on in Minecraft will be lost for good. I am NOT wasting money to fix a stupid issue like this that is not related to a virus because I will bet every electronic device I own that I do NOT HAVE A VIRUS. Someone, anyone, tell me how to fix this or I am done for.
P.S. I typed this whole thing on my Samsung phone.
