Stuck on "Installation required" Screen

[bullybilldestroyer-a]

So, yesterday, everything was working fine, but today, when I tried to start the app, it told me that installation was required:

So I clicked "Install". It seemed to work, and it gave me this pop-up:

But after I clicked "OK", it told me that I had to install again. So I did, but during THAT installation, I noticed something. It was running the command:
conda_hook && conda activate base && conda install nodejs -y -c conda-forge, but the nodejs was replaced by the name of whatever I needed to install each time, along with a different parameter. At each command, it threw this error:
'conda_hook' is not recognized as an internal or external command.'
