Slack not starting any more

Hi,
Upon the latest Slack update it’s not starting any more. Console output below. It appears Electron has trouble writing to a log file. Any clues?

OS: Ubuntu 20.04.

$ flatpak run com.slack.Slack

I have the same exact issue. Linux Mint:

$ cat /etc/os-release

PRETTY_NAME="Linux Mint 20.2"

Are there any fixes/workarounds?

OK, the issue seems to be with the latest Slack flatpak version: 4.26.1. After downgrading to 4.25.0 Slack starts again:
