Cant create a "Serverless VPC Access" on Google Cloud

I am trying to create a "Serverless VPC Access" on Google Cloud. I have already done it before on another account to join Redis with CloudRun.

This is an example of the configuration that I have tried

When the system is creating the connector, I get an error badge ,if I click this red circle I get the following JSON:

{
protoPayload: {
@type: "type.googleapis.com/google.cloud.audit.AuditLog"
status: {
code: 13
message: "An internal error occurred: Failed to create a VPC Access connector. Please delete the connector manually."
... 
}

I have tried different regions (us-central1, us-west1, etc...) and different IP ranges (10.8.0.0/24, 10.9.0.0/24, etc). I have tried with different minimums and maximum instances (from 2 to 10 instances). And I've even tried in different days of the week. Some forums say it is because the region is congested.

This is what I find in Google, there are few results, only 1 page of results

I found another forum where apparently no solution is reached

I suspect that it has to do with the antiquity of the Google Cloud account. Something that happens only for new accounts that have just a few days, because in the old accounts there is no such problem.

Thanks in advance.
