I no longer have information about the battery charge

The “Battery (pi-Top / laptop)” applet has stopped working. In other words, there is no longer any battery charge information on my pi-Top [1], with the latest OS. And in addition, in terminal, write the command
sudo pt-battery
the answer is as follows:
Error getting battery info: Resource temporarily unavailable
I suspect that this started to happen after the last updates.
Support, what’s up?
I appreciate a brief response please. Thank you
