Desktop app (Mac): blank screen without error messages when opening files

I cannot open files on my desktop app ( Figma Desktop App version 116.18.6 ). Unfortunately there are no error messages at all, just a blank, white screen with a loading indicator spinning forever.
At first I couldn’t see my home screen, either, but deleting everything in ‘Library/ApplicationSupport/Figma’ solved this problem.
Seems like I’m logged in correctly, all files and teams are listed.
Trying to open a file still fails – without any errors.

What I tried and didn’t help:
quitting the app and restarting it,
logging out and back in,
selecting ‘reload tab’.

Screen stays blank and white.

I’m using a MacBook Pro with Intel CPU and lots of RAM and free disk space.
Working in Safari Browser Version 17.4.1 (19618.1.15.11.14) also does not work correctly. I can work using Google Chrome.

My ‘shared ideas’: 1) please show error messages!! 2) fix the errors for Mac Desktop App

UPDATE: after writing the above post, I wanted to create a screenshot of the blank screen, and while I was dragging the screenshot rect… finally an error message popped up!!! “Connection Error -106, Your computer may be offline or the Figma server may be experiencing problems” plus a “try again?” Button.
So the desktop app seems to keep trying to load for ca. 10 minutes before showing an error message. This is way too long!!!
My suggestion: please change the timeout value to 10 seconds max.

Hitting the ‘try again’ button worked. The file loads fine and I can work.
Thank you
