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 disble 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:
