This function was previously deprecated, and is now removed. https://werkzeug.palletsprojects.com/en/2.1.x/changes/#version-2-1-0

2.0.0:

pbkdf2_hex, pbkdf2_bin, and safe_str_cmp are deprecated. hashlib and hmac provide equivalents. #2083

2.1.0:

Remove previously deprecated code. #2276

• Remove the pbkdf2_hex, pbkdf2_bin, and safe_str_cmp functions. Use equivalents in hashlib and hmac modules instead.

You should use a tool like pip-tools to pin your dependencies and control when you get updates. Be sure to run your tests with deprecation warnings treated as errors so that you get notified of these types of changes early.
