Pathauto causes password reset form error: Either the path '/user/123' is invalid or you do not have access to it.

Problem/Motivation

With the PathAuto module enabled, I cannot reset a password. Instead, I get the error message:

"Either the path '/user/123' is invalid or you do not have access to it."

Steps to reproduce

I am using Drupal 9.0.7 and Pathauto 8x.-1.8 module (4/20). I have the Simple Password Reset module enabled which allows me to reset a password without being logged in. The Reset Password page has a URL like /user/reset/1/token_string. After attempting to update the password while still anonymous, I get the above error message. Disabling the PathAuto module makes the problem go away.

Note: This may or may not be related to issue #3107695. Although I cross-posted my issue in the comments there, I am creating this as a separate issue as the other one is marked as closed and the original post's error message is slightly different. I have already tried the solutions to the aforementioned issue, but it does not affect my problem. I am also not using any multilingual/translation features.
