The only possibly-related information I can see there is:

  Jun 12 06:17:30 hero boltd[7027]: power: setting force_power to ON
  Jun 12 06:17:30 hero boltd[7027]: power: state changed: supported/on
  Jun 12 06:17:30 hero boltd[7027]: power: guard '3' for 'fwupd' active

which may be relevant because DisplayPort and Thunderbolt are the same bus, at least for Intel GPUs. So a few more ideas to try:

  1. Disable fwupd, with something like:

     sudo systemctl stop fwupd.service
     sudo systemctl disable fwupd.service

  2. Disable Night Light. There have been some bug reports, and suggestions from upstream, that gnome-settings-daemon managing the colour profile separately to the power state is causing some confused states.

  3. If all else fails, report the issue upstream: https://gitlab.gnome.org/GNOME/mutter/issues
