Bad environment variables messed up booting on Debian bassed (Raspberry Pi OS)

I set the wrong path in some environment variables, and now booting gives a whole new taste. The OS is *Raspberry Pi OS*, which is *Debian* based. **RESULT:**
Right after booting, I get a black screen with a mouse. Click any mouse buttons, and I get 2 options, "**reconfigure**" and "**exit**". "Reconfigure" doesn't seem to do anything. I hit "exit" and it feels like the program is being shut down and starting up again. I get a brief moment where I can do "ctrl" + "alt" + "F1" and I get to see for a brief second some command/Terminal code thingy, and then the black screen with the mouse is loaded again. (bad terminology, I'm am very new to Linux) **What I did:**
The bad thing I did was sudo nano /etc/environment and added a path to the **Vulkan_SDK** enviroment file setup-env.sh. (I had no clue how to do it), and this was incredibly stupid of me. PATH="path/to/setup-env.sh" **Content of setup-env.sh:**
