   Commit 0347da9 in 1.23.0 causes this problem.

   A simple test script:

   import UnityPy, os
   
   file_path = "path-to-your-file"
   
   UnityPy.load(file_path)
   
   try:
       os.rename(file_path, file_path + ".renamed")
       os.rename(file_path + ".renamed", file_path)
   except PermissionError:
       print("Occupied")
   else:
       print("Okay")

   Generally, one should not directly overwrite the file one is working with, one way or another.
   UnityPy tries to keep them as filestreams to reduce the ram usage, so as long as the opened stream isn't cleared by the garbage cleaner, the file stays actively used.
