Recurring Kernel Panic on iMac 2019

Welcome to the Apple Support Communities.

I believe we need to proceed with an EtreCheck report. EtreCheck is a useful App to diagnose and identify issues, both hardware and software. It is trusted by many users. Please follow the steps outlined below:

1. Navigate to: https://etrecheck.com and get the free version of EtreCheckPro.
2. Download it. It is a free and trusted app. It is often recommended here on Apple Support Communities. 
3. Open EtreCheck, and before running the report, be sure to check “Allow full Drive Access” at the bottom of the EtreCheckPro window.
4. Run the report, and put it in a post, as seen here: https://discussions.apple.com/docs/DOC-250000211. We will then examine the report for issues in your Mac.

Cheers,

Jack

No Time Machine backup! • It is extremely important to have a Time Machine backup. If you don't have an external drive for Time Machine, consider a high-quality, desktop-class 7200 RPM external hard drive, such as an OWC Mercury Elite Pro - MacSales.com (OWC).

Also, did you upgrade to 64GB of RAM when you purchased your iMac, or did you upgrade it yourself? If the latter, what brand of RAM did you use and where did you purchase it?

Cheers,

Jack
