Oil pan broken to drain screw – crack in thread

Hello, I recently wanted to make an oil change on my newly acquired (used) Yahama YZ125 2002. When turning out the oil drain screw, the thread of the oil tank came out with (rotation direction was the right one, which would probably already be slightly stained) – “OK, no problem, bigger thread in”. When screwing the now M14 (previously M12) screw the housing is torn (see pictures). Probably the thread cutter was no longer there. My question: What do I do now. As you can see in the picture, it is not possible to get this close. A eue tub costs a good 1000€, because the machine was needed is not worth it. I am very grateful for advice of all kinds. PS: Is my first post here, I hope I did everything right, if not with the criticism – topic I have so little n found suitable. Most handle only defective threads. Thank you!
