Welcome to the community.
What was the weight of the spool before and after you dried it? I ask because this image can also be attributed to moisture. Don’t assume that the spool was dry from the factory. In fact, Bambu has some of the shittiest quality control of silk.
Without a screengrab of the sliced object as it appears on your screen before it was sent to the printer, all we can offer is guesswork. Please post the screengrab in the preview mode so that we can see how the model was sliced before it was sent to the printer.
Now having said that and being able to only rely upon guesswork, this is the evidence that I see. This looks like the bottom of the model that was printed without supports.
Last comment. Silk is absolutely the wrong filament to use for structure parts. It is intended for “craftsy” purposes where appearance is the goal. Your image suggest that you are trying to make a structural part. Again, details of the model as it appears in the prepare screen would help us help you by understanding what the design-intent was of the original model. Again… details matter otherwise it’s pure guesswork.
