Mac Pro 2019 shuts down Panic CPU 0

Hello everyone, I'm looking to see if anyone is having the same issue am having with my Mac Pro 2019. It keeps shutting down after 5 minutes or so. I get the following report every time it boots up on its own.


anic(cpu 0 caller 0xfffffff0252211e4): "void AppleEmbeddedPCIeUpLinkMgmt::_functionInterruptAction(IOInterruptEventSource *, int): " "Completion timeout seen! [Device index = 0x0] [Link up = true] [CPL timeout = 0x0]" @AppleEmbeddedPCIeUpLinkMgmt.cpp:3659
