Hi Roxana, thanks for reporting this, it will be great to include at least the kernel version. So people can look up in the history more easily.
I believe this is for 5.4.0-1109-aws-fips
And I can see this from dmesg before it crashes:
[ 73.980713] ------------[ cut here ]------------
[ 73.980714] kernel BUG at arch/x86/xen/spinlock.c:62!
[ 73.981783] invalid opcode: 0000 [#1] SMP PTI

So this is probably a duplicate with bug 2029917
The system will be rebooted after that. And experiment shows the fail rate is 4 out of 5 attempts.
