Suggested Remedy for Windows 10 Conflict with Zonealarm after Windows updates?

after updating with windows 10 via KB5001716 and KB5037768 updates, I found the Event Viewer to show conflicts with ZoneAlarm Free specifically in CheckPoint related files and Windows 10 ran slower, and files began to take 1-2 minutes to open. However, there has also been an ongoing issue since an early update with Windows 10 Home Edition that I have seen CheckPoint Event warnings. Zone Alarm also will seem to freeze up. Please let me know if anyone has suggestions besides resetting Zonealarm, as I have multiple settings to block or allow various programs already.
