I also encountered this problem
I researched and found
I also use the WP Activity Log plugin
And it clashes with that line
do_action( 'lostpassword_post' );
In the file
frontend-reset-password/includes/somfrp-functions.php:343
the php error:
2021/06/14 17:53:12 [error] 1023#0: *9194672 FastCGI sent in stderr: "PHP message: PHP Fatal error: Uncaught ArgumentCountError: Too few arguments to function WSAL_Sensors_LogInOut::event_user_requested_pw_reset(), 1 passed in /home/petzaorg/domains/petza.org.il/public_html/wp-includes/class-wp-hook.php on line 292 and exactly 2 expected in /home/petzaorg/domains/petza.org.il/public_html/wp-content/plugins/wp-security-audit-log/classes/Sensors/LogInOut.php:543
