Windows 10: I can't seem to accesss my main user in windows after I install ubuntu

Okay so yesterday I installed Ubuntu in my laptop, thru flashing Ubuntu 22.04 on a pendrive and then loading it, allocated 100gb to linux and booted. At that time, I can access both windows and linux while booting. A window was coming which let me choose between linux and windows everytime I boot my laptop And I was successfully able to log in my windows user.Today, when I was logging in my windows user, the screen where we put in password was invisible, only the wallpaper of the lock screen was there in blurr, with power and wifi settings in bottom right. I was not able to put in the pin. Aft

Can install Windows, can't install Linux

Are you doing a clean install?

Also if you are doing a clean install may I suggest this. Delete and format all partitions and let Ubuntu allocate the drive. You might have some MBR files left on the HD that is conflicting with Ubuntu booting.
