This issue can cause due to expired trusted root certificates in the vCenter that the customer is trying to convert. This blocks the trust establishment step in the convert workflow and prevents the guardrails from operating normally - leading to the vSAN python guardrails returning INTERNAL_SERVER error.
Need to clean up the expired certificates to execute guardrails phase correctly.
Please refer KB to remove the expired certificates in trusted root store of VC :

Then attempt convert again.
