Error When changing status in opportunity, the status has a event notification

Hello,I’m using version V12.4.1. I’m working in an opportunity. I’m able to create the opportunity successfully, but when I change its status—for example, to “In Progress”—I get an error.Please note that I have an event notification configured for this status, so it seems to crash when it tries to send an email during the status change.

i tried V12.4.2, i get the same issue

Here is the error in Projeqtor Log File
