Slack repetidamente não está respondendo

Question

O Slack entra no status "Não está respondendo" várias vezes por hora. Esta é a mensagem Geral do Visualizador de Eventos.

The program slack.exe version 0.34.3.0 stopped interacting with Windows 
and was closed. To see if more information about the problem is available,
check the problem history in the Action Center control panel.

Como faço o Slack não travar?
