Getting a 'black screen' following matches in the Standard Ranked queue.
Just had to ALT-F4 to close Arena and my latest log file is attached.

heres your log black screen

Hey, at first it was ok and I was able to join premier draft, but after one game screen went black and it stays that way even after client restart. Logs attached.

Hit Alt-F4 because no other resolution. Thanks for working through the issues and look forward to the fix.

Same issue!

I am tired of the crashes

Worked once on my Mac, then black screen every subsequent launch. I've uninstalled and reinstalled through the Epic games client.

Estaba jugando draft premier pague 10.000 de oro y en cada partida se fue a negro al final perdi las 3 partidas

Same here, I lost the first Game in sealed. Game Crashed, after a few minutes i could access again in Main Menu. I went to Sealed-Screen and saw First Game loss! I tried to start a new match, after starting the opponent said "Hello", i tried to answer, immediatly i clicked on "my face" the game crashed and again I couldn't get back to the game. I didnt try it again to start, but i am sure the second match is lost too!

In my humble opinion, it is not possible to pay anymore money, if the players and me wont get back the Token. 50 bucks are a freaking high amount of money and i only paid it, because i love WOTC and want to support it. But not like this!

Been happening all day

Here's a log for the black screen issue.

Black screen on trying to load client. Only cursor is visible.

Here it is...
cheers

Here's a log for the black screen issue.

More log files to add to the situation. Black screen happens most times I start. I actually was able to reach the options menu/move past the black screen this last time by hitting Esc a few times. Only other time I was successful in logging in normally, the friends/social feature was showing "User#12345" as my account name and said I was offline/would need to go online to see friend features.

Having issues with it black screening after building or modifying a deck or upon completion of any match. Also black screens on opening 3/4 times, the 4th letting me do one of the above stated actions before repeating the process.

Black Screen at startup, after games, switching from Decks tab to any other tab. Sometimes daily/weekly achievements don't appear.

Black screen after I started a draft! OMG

black screen on load-up of client (sometimes the client opens after a long wait time, sometimes the screen just stays black)

black screen after a game ends (client's main screen never appears)

The crash report that was generated upon opening the game. After this crash, I log in and just get a black screen. I'm unsure of where the non-crash logs are on the mac client.
