MODX 2.8.4 with PHP 8.1.5, 500 ERROR

[redbull10]

Error message

500 ERROR, no page shown when right clicking to update user fields in manager.

Summary

I have broken down the problem to be with the "OnUserFormPrerender" in the HybridAuth plugin. When disabling this, the user edit field page is shown, but not the tab "Auth Providers".

Step to play

Upgraded from MODX 2.8.4 with PHP 7.4 to PHP 8.1.5.

Observed behavior

Generated tab "Auth Providers" in user user edit form in manager breaks everything. Resulting in a 500 ERROR.

Expected behavior

It should work as normal.

Environment

NGINX
PHP 8.1.5
MODX 8.2.4
Latest HybridAuth

Forgot to mention that it works nice with MODX 2.8.4 with PHP 7.4
