Hi,
I checked the requested Windows Event Viewer logs and found the following.
Applications and Services Logs > Microsoft > Windows > CodeIntegrity > Operational
I found nothing relevant.
Applications and Services Logs > Microsoft > Windows > AppLocker > EXE and DLL
I found nothing relevant.
Applications and Services Logs > Microsoft > Windows > Windows Defender > Operational
I found Event ID 1151, Endpoint Protection client health report.

I also found the following event from EA Javelin AntiCheat:
Event ID 1000: fc26.exe exited unexpectedly with exit code 0xFFFFFFFF
There were no relevant events in CodeIntegrity or AppLocker, and Windows Defender shows that real-time protection and the other protection components are enabled.
The Javelin AntiCheat Event ID 1000 is the only event I found that directly reports FC 26 exiting unexpectedly.
