This error message came up in April:

It's hard to be sure that the cause is the same without knowing more
about the setup.  In that case the cause was multiple threads or
processes trying to refresh the ccache from a client keytab at the same
time.

To address this issue, I implemented atomic replacement for most
credential cache types:

However, it will be some time before this works its way into a Kerberos
for Windows release.  I'm not sure I can offer concrete advice since I
am not familiar with PowerBI.
