Energy stops regenerating. This occurs intermittently.

This has been happening for several days. I wasn't sure about it at first because I'm constantly logging in and out and switching computers. I couldn't be sure that I wasn't just using it up as quickly as it was being regenerated. When I stopped playing last night, I had around 9 energy remaining. When I returned 7 hours later, I had only recovered about 20 energy.

Once the energy stops regenerating, it will not automatically restart. If I log out and back on, the energy will start regenerating again at its normal rate but it does not recover the energy lost.

Windows 10 and Windows 11 are both affected.
