Context: I am running the 32bit full Raspbian OS on the raspberry pi 4 as a desktop, the newest version. Whenever I open chromium, the default web browser, it simply opens a window. When I tried to open that window, it would open briefly and disappear. Similarly, I'm getting this type of action with Mu, a default python IDE for raspberry. I thought this could've been an issue with all my apps on my PI, but when I tried running some generic default games, they seemed to work fine.
My Troubleshooting: I've had chromium working previously, but now it's not working. I've checked all updates and upgrades. This hasn't led me anywhere. I've tried almost every way to update chromium (like 2, not really every way). I then resorted to deleting the browser via purging it from the system. I then tried to redownload, issues downloading.
After purging chromium, I get a new default browser, firefox. When I try to open firefox, it just completely shuts down my entire system.
My team and I are noobs with Linux and raspberry Pi, so if you have a potential solution, please make it such that we can follow along like the copy and pasting wizards we've become.
