Hello,
Same problem with forest in 2012.
We found that the problem does not occur with AMD-based instances, only with Intel EC2 instances.

If we transform the instance into m5a.xlarge the instance can boot and operate in the domain again.
We have not really found an explanation for this behavior, as if joining a domain with Intel CPU blocked the instance from booting when no GPO is applied.
With WS 2022, we have no problem, only 2025 with Intel CPU...
Confirmed the instance type change works! Went from t3 to t3a, success. Wow. Great catch!
