A few days ago I went to boot my trusty Raspberry Pi model 3b (I know, it's a bit outdated) after quite a few months of not using it, and I was going to connect to it in a headless configuration, but I noticed that I couldn't connect. I had to get some other stuff done, so I only came back to it today to investigate. It booted like normal, and it went through all of the normal screens and processes of a boot. I thought that all is well, until I noticed that instead of showing me the Raspbian desktop, I got a blinking cursor. It is not a command line, and I can't type anything in. The green light is also fairly active, blinking every few seconds. Interestingly, while I was off writing this post, the green light has stopped blinking and the flashing cursor has disappeared. It seems similar to this post Rasberry Pi Black screen after boot wth blinking cursor.
If I can remember correctly, the last few times I was using it, I could not boot into it properly, but only VNC or SSH into the Pi.
I know that I could probably just format the card and flash Raspbian or NOOBS onto it. It is not necessary but it would be nice if there were any way that I can at least recover some of my old files.

8GB micro SD card
For any reading/writing to the micro SD card, I have a both a Windows and an Ubuntu machine.
Thanks in advance.
I will check back here often, and I will edit my post to include any required information
