Thank you for the information Miguel Galán . I have faced the issue twice now while calling a!startprocess from a button component in last one month. Nothing was changed but the issue just occurs and resolves itself. This explains why.

In case this help, today, I opened an Appian Support Ticket due to in my client we have the same problem.

Paste here the answer Appian Support report me:

"The start process smart service has a defect that is only exposed under certain levels of load which explains why it's successful & or errors out sometimes. Under high loads, the java work queue may result in a race condition. The smart service is asynchronous whereby it does not wait for the completion of the process(es) it started but its mechanism that calculates the process info is synchronous.
To ensure that this change is delivered in the least disruptive way possible, we are addressing this through a future feature release targeted for 24.4 Excitingly, this feature will not only address the root cause of this issue, but it will further introduce optimization and customization possibilities for the start process smart service and a!startprocess function. To leverage the feature release to address this issue, you will configure the start process to use the new Start Process Smart Service node. "

Can you share a screenshot of the node configuration?

You know that you need to pass the data using a map or dictionary?
