I tried to run a diagnostic on my MacBook Pro, but holding down d didn't work. I tried option+D and got "Starting Internet Recovery" and then it said "Run Diagnostics" and asked if I wanted to "run offline" or "I agree". I tried both options. Then my mouse froze and nothing happened. I'm trying to run a diagnostics on my battery and nothing is working.
MacBook Pro 13″, macOS 10.15
Try an SMC reset.
Option-click the battery icon on the menubar. Any condition other than "Normal" or "Good" means the battery is either wearing out or bad. "Service Battery" or "Replace Now" indicate either macOS has detected a fault with the battery or the battery is completely worn out respectively.

Try running Apple Diagnostics with a charger plugged in, this usually resolves issues with Apple Diagnostics.
Check How to use Apple Diagnostics on your Mac – Apple Support for steps on how to run Apple Diagnostics.
My power adapter is plugged in. Unfortunately, if I unplug it my computer shuts off (there seems to be a problem with the battery). But I can't run the diagnostics to figure out what the problem is.
