0 Class "gridboxHelper" not found after update to 2.18.0.1

Hello Balbooa, since yesterday I have a problem with updating the gridbox. After uploading version 2.18.0.1, I cannot enter the Gridbox panel. I see the message 0 Class "gridboxHelper" not found. If I manually upload version 2.17, everything returns to normal. Joomla version 5.1.2
