anaconda – Conda Not Using Expected, Base python.exe

I ruined something in Conda that now has disabled my anaconda prompt. I believe some change occurred when I attempted to add an interpreter to Pycharm. Unsure what I did wrong, but now when I open an Anaconda Prompt (Windows Start –> Anaconda 64 bit –> Anaconda Prompt (anaconda3)) the CL prompt opens, but the normal Base environment is not activated. Attempting to activate it or another environment yields the below error.

Python path configuration:
  PYTHONHOME = (not set)
  PYTHONPATH = (not set)
  program name="C:\Users\\anaconda3\python.exe"
  isolated = 0
  environment = 1
  user site = 1
  import site = 1
  sys._base_executable="C:\\Users\\\\anaconda3\\python.exe"
  sys.base_prefix = 'C:\\Python27\\ArcGIS10.8'
  sys.base_exec_prefix = 'C:\\Python27\\ArcGIS10.8'
  sys.platlibdir="lib"
  sys.executable="C:\\Users\\\\anaconda3\\python.exe"
  sys.prefix = 'C:\\Python27\\ArcGIS10.8'
  sys.exec_prefix = 'C:\\Python27\\ArcGIS10.8'
  sys.path = [
    'C:\\Users\\\\anaconda3\\python39.zip',
    'C:\\Python27\\ArcGIS10.8\\DLLs',
    'C:\\Python27\\ArcGIS10.8\\lib',
    'C:\\Python27\\ArcGIS10.8',
  ]

I use a program called ArcGIS, and at one point a million years ago I had to edit some Python or Conda Configuration-like file to include a path to enable license permission to a closed-source module. I have since forgotten that protocol, but perhaps that is the reason for the Conda’s attempt to use it’s executable(?) which is being populated as a sys.path.

I’m lost, would highly appreciate any ideas.
