Azure: what could be the cause of the error "Unable to edit or replace deployment"?

Question

When I recreate my VM I got the following error:

Problem occurred during request to Azure services. Cloud provider details: Unable to edit or replace deployment 'VM-Name': previous deployment from '8/20/2019 6:20:33 AM' is still active (expiration time is '8/27/2019 5:17:41 AM'). Please see https://aka.ms/arm-deploy for usage details.

Help me please to understand. What could be the cause of the error ?

UPDATED:

This deployment has not been started previously. Prior to this, errors were received during creation:

Azure is not available now. Please Try again later

There were several such errors one at a time and then I got that error related to:

Unable to edit or replace deployment

My assumptions about this. Tell me, am I right or not ?

I launched the image, then after some time I recreated it. Creation began, but at that moment the connection with Azure was lost. Then, when the connection was restored, we tried to make a deployment that was not removed in the previous attempt (because there was no connection with Azure). As a result, we got such an error.

Does this theory make sense?

This can also occur if you use Bicep templates for your ARM deployement and multiple modules or resources in the template have the same name:

module fooModule '../modules/foo.bicep' = {
   name: 'foo'
}

module barModule '../modules/bar.bicep' = {
   name: 'foo'
}
