critical error with ‘my booking’ PHP 8.1

Hello,
‘Mybookings’ page crashs if running PHP 8.1 but works with PHP 7.4.
I am using EM Version 6.1.3 / WP 6.1.
I am currently stuck with issue as I have to use PHP 8.0 for other plugin.
Thanks to look at this problem

When running PHP 8.1 I got the following error:
