Cloudformation stuck in UPDATE_ROLLBACK_FAILED

Please help get past this. I have to enter 3 logical ids to rollback my update, but the regex in cloudformation doesn't allow for that because the regex doesn't appear to allow commas. But the continue ROLLBACK instructions from AWS clearly state to use commas: "To skip resources, type a list of comma-separated logical resource IDs. Include only the resources that are blocking the rollback."

But the commas are not allowed???? What am I missing here? I can't go forward or back. My stack is stuck.

My error on trying to roll back:

Failed to rollback: 1 validation error detected: Value '[rRoute10,rRoute192,rRoute172]' at 'resourcesToSkip' failed to satisfy constraint: Member must satisfy constraint: [Member must satisfy regular expression pattern: [a-zA-Z0-9]+|[a-zA-Z][-a-zA-Z0-9]*\.[a-zA-Z0-9]+]

My errors in cloudformation:

For background, someone deleted our VPG and created a different gateway. They also manually updated the routes. Now, I am trying to get the stack in sync on the route tables. However, the stack failed to update and now it fails to roll back.
