Black Screen after dim/sleep

I am using Ubuntu-based KDE Neon and recently added a new user to my machine. Ever since I added the new user, whenever the machine goes to sleep - usually due to inactivity - the screen stays black, no matter what I do. The only thing that is visible is the cursor and it disappears when I press escape key and appears when I press anything else. This laptop has an AMD Ryzen 7 3700U with Radeon Vega Mobile Gfx. I do not dual boot and kernel is Linux 6.8.0-52-generic x86_64, the operating system is KDE Neon 6.2 with release 22.04 (jammy), and the laptop is an Asus VivoBook X512DA.
