hi @Aminko_1  
Maybe the workaround in this post will help.  
Please follow this post as this will hopefully be looked at by Epic Support

Hi Aminko,

Try checking again, you might need to restart your Epic Games Launcher.

An update triggered for me, It’s still reporting as v37.00, but if/when you are able to launch you can hover over the version number in the upper right and see that it was built recently. (Aug 12)
