1. Restart the Slack App

The simplest fix is to restart Slack completely.

Sometimes, temporary glitches cause Slack to stop loading properly, showing a blank white screen.

3. Update Slack to the Latest Version

An outdated Slack version may be incompatible with the latest system updates, causing issues like a blank white screen.

• Open Slack and click on Help > Check for Updates.
