I can't access my Realm world at all, please help!

This is a bug report on the Switch version of Minecraft.
After updating the Switch console to 18.0.1 and Minecraft to 1.20.80, an error occurs every time while loading graphics right after the loading screen when entering the Realm world, forcing me back to the Switch home, so I cannot access the world at all.
I have repeated the attempt at least 6 times with the same result.
