I'm using the OpenCore setup to run Catalina. I noticed this on both Mojave and Catalina, when I download a large file through Safari, sometimes the hole Mac freezes and the only way I can continue is to press and hold the power button. This is a stock install, the only extension I have installed is AdGuard for Safari.

Mojave is on a Samsung 850 EVO SSD on first SATA slot and Catalina is on a Samsung 970 EVO Plus NVMe mounted on a Syba PCI card.

Anyone else experienced these freezes out of the blue? I ran a hardware diagnostic, no issues.
