Ubuntu 20.04 зависает и вылетает

Недавно я обновился с версии 18 LTS до 20 с помощью обновления программного обеспечения, и с тех пор замечаю случайное зависание или сбой системы.

Симптомы Сбой обычно начинается с полного зависания некоторых окон (без ответов) (по сравнению с кодом или firefox), и за короткий период (30-60 секунд) вся система зависает, и единственный способ продолжить - перезагрузка с помощью кнопки питания. В последнее время я также заметил несколько мгновенных сбоев, когда весь экран стал черным. Я также заметил, что сбой обычно происходит при использовании кода firefox или vs (но не при намеренном выполнении жестких вычислений).

/ var / crash

Самому последнему файлу 3 дня, последний сбой был сегодня.
