Omega not showing update console

No. To find Omega Shenron you go to Central/West City and fight Gotenks. After than Omega Shenron should show up to fight,.

the contact omega is not showing up in game gta 5

Instead of leaving the Xbox Insider program as one Ambassador has suggested you can drop down to a lower ring which receives much fewer updates. For example if you are in Beta ring drop down to Delta or Omega. The Omega ring receives the fewest updates,
usually just before it is released to the general public. This can be managed using the Xbox Insider Hub on your console.

Okay, can you share the feedback link here, please? I’ll ask the team about it.

The Insider update should’ve improved the performance, so it’s strange that it hasn’t made any difference. If you joined the Omega preview, this is the most recent update (it’s possible that it installed automatically by itself if the option to keep your console up to date is enabled):

Here to help.

As I mentioned, if it's not among the ones listed, you should use OSU1

Except that the OP is running an Insiders build (the OS build information is the latest Insiders update) so your advice will likely lead to a broken console!

What the OP posted is a match to the lastest Omega ring update (also seems to match all the updates from all the rings) from 4th February, unless I am missing something:
