Everything is blue when a world is opened

When I import a .mcworld file to Minecraft, it imports successfully. But there's one problem that annoys me a lot! EVERYTHING IS BLUE! (See the attached screenshots) Yes, there are NO resource packs, but everything is STILL blue! This does NOT happen in just ONE world, it happens on EVERY worlds that are imported from .mcworld file!!!

 

This is really annoying! Mojang, please fix this bug!!!!!! (This never happened on the previous versions of Minecraft)

 

MY PC SPECS:

8GB RAM

512GB NVME Gen3 SSD

Intel Core i7-10510U (4 cores, 8 threads)

Intel UHD Graphics (Integrated Graphics)

NVIDIA GeForce MX350 (Dedicated Graphics)

1920x1080 75Hz IPS LED display

 

NOTE: According to the screenshots given below, all the worlds use different addons, and EVEN without addons, this problem occurs. This is NOT a problem with my PC specs, this is probably an issue with Minecraft, since this problem didn't show up on the previous versions of Minecraft.
