Ubuntu 20.04 зависает при использовании Teams через браузер Google Chrome

Я только что установил Ubuntu 20.04 (около 5 дней назад, так что довольно чистая установка) и когда я использовал MS Teams через браузер, он работал нормально для начала, а затем около 20 или 30 минут в совещании мой весь графический интерфейс ОС замерз, и я не мог ничего использовать.

Когда я собирался выступать на собрании, я сделал жесткую перезагрузку, чтобы попытаться вернуться на собрание, что мне и удалось, однако затем снова произошел сбой. На этот раз я оставил его, и в конце концов, примерно через 15 минут, появилось диалоговое окно "Извините, Ubuntu 20.04 столкнулся с внутренней ошибкой", и графический интерфейс был разморожен.

Я приложил журналы "Все" и "Важные", а также снимок экрана из диалогового окна сбоя.

Второй сбой (к которому относятся эти журналы) произошел в 13:54.

Любая помощь в определении проблемы будет очень признательна! Спасибо.
