Daedalus rewards wallet does not start

hi someone could help me with the wallet daedalus rewards, in when it does not start, the boot screen loads but after a while the form to contact the support appears.
I installed the wallet on both windows and Ubuntu, but both have the same problem.
On what can this error depend?

Do you have the latest version? You can check and update if necessary here.

The support contact notice appearing is not significant, it happens automatically after a certain time.

Connecting sometimes takes quite a while, I minimize the window and forget it for an hour or even two, it nearly always connects eventually.
