In the attached video, I start with a 116 Miner Workgroup, everything is connected to Pumps and a singular power grid.
There is a 64-block range Quarry Scanner, and all Miners have Silk Touch Mining Lasers with 64 Mining Pipe.

It will occasionally get stuck after starting the Miner Workgroup.
When this bug occurs, the Master Miner shows a progress value of "6.6k / 200 t".
Additionally, the Miner never enters a "Stuck" state, and will just constantly drain power.

After "refreshing" the Miner by replacing the Mining Laser, it will resume its task as normal, until the bug randomly occurs again.

World after the bug occurred a second time, in case you need to open it up and see what is wrong:
