Raindrop closes on opening on mac os x 10.11

[MacTerrassa]

On an iMac with an updated 10.11 operating system, the latest version closes immediately when you try to open it. I do not see any diagnostic report in console, but if the following lines:

I have first tried deleting all raindrop folders from my user library, with the same result.
The previous version does open, but it is automatically updated to the same unusable version.
I do not understand that mania with forcing everyone to update, especially when in many cases they end up with an incompatible version.

I'm talking about version 5.4.2 of Raindrop

Is it a bug in the program that you can fix, or have the requirements changed? I think that in another mac with Catalina I have already updated without major problem. Do they really check to see if the program is still compatible or is it totally random?
