[System Version]: deepin V25.2.2 In addition to the previous inquiry. An error was made in the OS version specification — 25.2.1. Today, an update to version 25.2.2 was downloaded, and as a result, the issue was resolved: the keyboard in the Libre Office Writer, Mozilla Thunderbird, and Terminal applications began to switch correctly. Numlock remains in the ON position after reboot. The situation remained the same only in the Google Chrome browser, but after updating the browser to version 152.0.7977.82 via Deepn Store, the error disappeared there as well. Thank you very much for the quick correction of the errors.
