if you haven't earned coins and you have Windows you can follow these steps:
close the Gui
go to \ .chia \ mainnet \ wallet and delete only the files starting with "blockchain"
reopen the Gui
this process worked for me.
Also a new version of the Gui is available.
You could try to install the new version first and if it doesn't work follow the steps I wrote to you.
Hope you solve!
