Python Selenium Chrome - Message: unknown error: cannot parse internal JSON template: Line: 1, colum-CodePudding

This code works on two PCs but throws an error on another one.

webdriver_path: str = os.environ.get("WEBDRIVER_PATH")
chrome_user_data_dir: str = os.environ.get("CHROME_USER_DATA_PATH")
chrome_profile_dir: str = os.environ.get("CHROME_PROFILE_DIR")
options: webdriver.ChromeOptions = webdriver.ChromeOptions()
options.add_argument(f"user-data-dir={chrome_user_data_dir}")
options.add_argument(f"profile-directory={chrome_profile_dir}")
driver: webdriver.Chrome = webdriver.Chrome(executable_path=webdriver_path, options=options)

I get the following error:

I saw the same question asked with very few answers that didn't solve the problem. Tried deleting /Preferences and /Local State in the chrome user profile directory. Tried reinstalling chrome and chrome webdriver. Tried with different selenium versions. Nothing seems to work for now.

Any ideas or solutions that you used for this problem would be very helpful. Thanks in advance.

I managed to get it up and running again! The solution that worked for me was deleting C:\Users\USER\AppData\Local\Google\Chrome folder and reinstalling Chrome. If you run into this problem, give it a try.
