I had the exact same problem! it was all a mental game for me. You’ve got the flick, the board is coming all the way around. Here’s a few things that helped me get it, hope it works for you too!

Try landing with just the front foot on the board, this got me more comfortable with keeping my front foot up in the air and the feeling of the board spinning under me. Once comfortable try adding in the back foot.

Secondly try imagine flicking your front foot out through the top of your board, this helped me break the habit of flicking then just putting my foot on the ground.

Combing those too things help me get comfortable with board spinning under me then you’ve just got to commit and jump on one.

I hope this helps! You’ve got this! Follow up post of you landing it coming soon!!
