When this happens, either you have run out of energy, or other aspects of you are projecting and sucking up all available energy, causing paralysis.

Regular practice with some energy work will overcome this.

It will also help if you speak commands to your higher self. 'Give me light' 'Give me movement' 'Give me motion' and affirmations like 'I can move easily and fluidly'

I suspect this type of paralysis issue happens while the astral body is growing and developing. That's a good way to look at it. Give it time and pay it some attention and all will be well in time.
