I am getting this error for Alise's 006.png, as well as for the portraits as well.
This is on 5.24c,
OpenGL ES 2.0 Renderer: GeForce GT 740/PCIe/SSE2
ERROR: No loader found for resource: res://files/images/alise/006.png.import
At: core/io/resource_loader.cpp:285
Opening Alise otherwise has no issues, it is just her initial introduction that is not appearing, I see her black shadow but not her until after she finished introducing herself.
