So if you ride a strider a little far away from your respawn anchor and then die while still riding it, if you go towards the place where you died, you get a interesting bug where you get teleported back on the strider but you can't mine blocks, place blocks, drop items and load chunks but you are still vulnerable at the position before you got teleported.

Here is a video about the bug:
