Fatal Error with buddyboss-platform

Seems when using buddyboss-platform there is a conflict with one of their functions

PHP Fatal error:  Uncaught TypeError: call_user_func_array(): Argument #1 ($callback) must be a valid callback, function "bp_member_switching_clear_olduser_cookie" not found or invalid function name in /home/nginx/domains/domain.com/public/wp-includes/class-wp-hook.php:312

@jcatello that error is from WP trying to call a function that is hooked to the filter by name, but does not exist at the time the filter runs. It can be reproduced locally via wp shell like so:

wp> add_filter('my_filter', 'does_not_exist')
=> phar:///usr/local/bin/wp/vendor/wp-cli/shell-command/src/WP_CLI/Shell/REPL.php:52:
bool(true)
wp> apply_filters('my_filter', 'foo')

They're probably hooking the function on the filter by name in one place and loading the function somewhere else so that when it's triggered by the login command that the function referenced isn't defined.

Closing for now as this appears to be an issue in the buddyboss-platform plugin.
