After updating my world to 1.18.0 it became corrupted and won't load.

After downloading and installing Minecraft 1.18.0, I went to load in my world that was last saved during the Minecraft 1.17.41 update. I updated my 1.17.41 world to 1.18.0 and made a backup. When I loaded into the world, some of the textures would not load. The textures I remember not loading were, warped nylium, water, netherbrick fences, warped wart blocks, and weeping vines. The textures were displayed as black and pink checkered patterns, except for water, which appeared as a dark blue/purple checkered pattern. I saved and quit in the hopes that the textures would load, but when I tried reloading the world I was met with the message: "You are out of data storage space and Minecraft is unable to save your progress! Minecraft will return you to the Main Menu to clear up storage space." I was not out of data storage before installing this update and the storage bar still shows itself as less than half full. Moreover, I'm not able to play my backup world without being forced to update it to 1.18.0 as well which I feel defeats the purpose of creating the backup in the first place.
