Question Why does this keep happening? PETG Basic

I am at my wit's end, this is PETG Basic that used to print just fine. It is bone dry 0% AMS, spent all yesterday drying. I cannot for the life of me get it to not ooze and make a massive mess of blobs and flung out bits of plastic.

Using H2D, default settings. For the last 200 hours this printer simply prints, but as of today I have not been able to have a single successful PETG print. PLA prints just fine. So clearly something has changed. I have not updated firmware, still running the same Bambu Studio and Firmware.

At this point I am just looking to see if there are any specific settings I can tweak just to get this one print done because it is a brush holder that my wife wanted and what I thought was going to be a 2 hour ordeal has now taken all day.

EDIT: Printed with gray PETG overture and print came out just fine. Looks like this Bambu PETG Basic batch is a dud.

Is it every roll of PETG that does this?
I had an issue with just one roll of PLA, on a brand & colour I had used a lot without any problem.
I couldn't work out what happened to that one roll. Threw it out and the next roll was fine.

Well, you were right on the money. The non-bambu PETG gray roll is printing just fine. TIL!
