After 1.18.30 was released the animations of certain blocks have been broken. Removing and adding resource packs has for some reason changed which blocks have broken animations and which ones worked correctly, but it doesn't seem to be doing that any more. I use a lot of different resource packs so maybe this has something to do with that. However, upon removing all resource packs and global resources some blocks still had broken animations. Here is a list of the block animations that are currently broken for me:

• Nether portals
• Respawn anchors
• Magma blocks
• Stagnant water
• Stagnant lava
• Flowing lava
• Stonecutters
• Soul Fire
• Fire
• Prismarine
• Lit Smokers
• Lit Blast furnaces
• Top texture of a downward bubble column
• Middle texture of a downward bubble column
• Outer texture of an upward bubble column
• Middle texture of an upward bubble column
• Water and lava cauldrons
• Soul lanterns
• lanterns

All other Block animations are working normally.

Edit: "Broken" as in some of the texture animations are stuck on one texture. I have added a video. I hope this helps.
