I can't see clearly, but if it's caused by light, there are two ways. One is to find the layer where the shadow appears, turn on the texture option and choose to turn off the shadow. The other is to find the layer that produces the shadow, turn on the texture option, and select Close to accept the shadow. If it's a homemade shadow, just delete it.

There is another one, hehe, modify the lighting properties, and do not check the cast shadow.
