i downloaded the 1.17 release expecting to see a new title scree panorama but i got the old 1.16 panorama instead

idk if this is a launcher problem, but i even unzipped the 1.17 jar file to get the assets foler and what i saw was that in the gui/panorama folder, there are 6 pics as usual, but they are 1 PIXEL ONLY!! im sad. also, the gaurdian lazar beams arent showing, like its not showing the orange to green lazar, its only the bubbles around it.
