php_opcache crash - memory access violation

Description

I don't know how to recreate the problem. it occurs on our production server, sporadically. 6x in past 4 days. never happened on old server (Windows 2012 R2) running same versions of PHP (8.0.14 x64 thread-safe) and apache httpd (2.4.51 x64), and the same opcache configuration. We are not using JIT.

Windows Event Log shows:
