Resolve 15 Doesn't Export

I have finest experience with Resolve 14

Three days back I have installed Version 15.0b4

Graded 3 mins footage

and tried to export it but resolve show remaining time as 26 days within minutes

I have thought that it will reduce after few minutes

But its still goes on to 46days

Tried in various settings result was same..

even I have tried with uninstallation - installation process but again and again result was same..

Please help me

You could try beta 7 too

Have tried to beta 7 too..

but whole project went to offline

tried to link in various methods but whole timeline files says "mediaoffline"

finally my problem solved in partially way

Export happen in individual clips..

but resolve still has problem to export a project in single clip..

Thank you
