My Nreal Air display flickering

I have problem with my Nreal Air glasses.
My right display are flickering.
I bought them in England in AA store.
The glasses worked great for a couple of months, now they started causing problems. Can you help me? Thanks in advance

Hi, could you please try to update the current firmware by the following page, and please note that DP is required to update.

My glasses are allready on latest update.
I tried to update, but it is saying latest update instaled.

Thanks for this further details. I found that the firmware is the latest, and it is OK for use. If the issue only happens on the Right display by this firmware, then please try to replace the current glass.
