Hi all, advice needed on the issue in the video. If I put down pressure on the crank the whole Axle & chainring spider mount has some play in it.

In the video I am pushing on the chainring towards / away from the bike and you can see there is 1-2mm movement each way. Both the axle and chainring spider mount move together so it's not the lockring just not being tight enough.
Any ideas? Thanks
