error open urandom

[RoyZhang2022]

I am using AWS SDK to develop an ODBC driver. Our code is running on github. The test works fine locally on Ubuntu 20.04. It also could run successfully until Aug 9. But from yesterday the test on github starts to fail like below. It is from Aws::InitAPI(). As it is AWS SDK code we have no idea what is wrong. Just from the error info it seems /dev/urandom could not be accessed.

One more thing we noticed is the aws-c-io which calls s2n is updated from 0.10.7 to 0.10.22. Not sure if this causes the problem. Please help to have a check. Thanks!
