Same problem on Mac bought in 2019.

Processor 1.4 GHz Quad Core Intel Core i5
Graphics Intel Iris Plus Graphics 645 1536 MB
Memory 16GB 2133 MHz LPDDR3
MacOS Sequoia 15.0

I had the issues before updating to Sequoia from Catalina.

Good morning, after the latest MTGA update (25 September) on macOS Sequoia 15.0, the program starts but crashes shortly after (during the loading of the initial scene). On the Android version on my mobile, the game starts up regularly.
What I don't understand is that this should be a widespread issue on all Apple PCs, at least with macOS Sequoia 15.0, linked both to latest MTGA update 2 days ago, which followed Apple's update a couple of days earlier (until 5 days ago, I was using macOS Sequoia 14.7).

Before the latest update, and with macOS Sequoia 15.0 already installed, the game was working perfectly. Therefore, the update was faulty.

someone say to use REVO uninstaller for clean the game and reinstall. AFter log in from different device and relogin iinto your main computer .
Can someone try this?

Same issue, both on PC and Steam. Especially in deckbuilder and store. Reinstalling doesn't fix it. Destroys all the fun and I have basically not played at all in the last weeks after playing nearly daily for almost 5 years. Please fix asap!

I have been having this same issue and haven’t been able to play, open store, purchase gems, etc for two weeks

Phone app works but i hate to purchase on small screen as of sept 12 i can not open packs or make purchases on the desk top.
I tried a sealed token event and could not open packs to even build the deck.

Still not fixed after today's 10/2 update. :(

I have definitely been having the same issues the last 2 days. Game freezes mid-game...then it crashes. I get back into my game but sometimes it happens again to the same game. This is about 5 times now in the last 24 hours 10/2. I'm only using a PC when I play. No mobile devices

still not fixed even after update..

When I click on packs icon the screen begins to flash. It’s glitching so hard even when I force quit the program the background screen is still flashing with a ghost mark of the arena screen when the app isn’t even running. Using updated iOS on MacBook Pro.

I have the same problem.
I tried uninstalling and reinstalling the client but didn't work.

Experienced this issue for over a week on Windows 11. Uninstalling and reinstalling the client did not help at all, nor did "Validate Bundles". What does seem to have eventually resolved the issue is changing the graphics settings from Custom to Medium.

]Just manageg to reproduce this bug by installing on a new separate Windows 11 machine. Funny thing is, it only works for me within a Lutris Linux environment.

I tried the 'Validate Bundles' and didn't work as suggested below. Also tried windows updates, optimising my drives and deleting and re-installing the game but nothing worked. Why haven't they fixed this after more than 2 weeks!!?? Isn't PC the main platform for this game? Really poor.

Still not fixed? Everytime that i have to open a pack or open a store, or even claim some rewards, i have to open on my mobile, because on PC always crash it.
It sucks, everything wotks just fine, but this is extremely annoying.

As soon as I start a draft with people in the best of one, it crashes and in many games as well. I have lost draft games and consequently gems due to these problems.

On windows 10 here, Intel HD 620 graphics. Validate bundles made no improvement. Rest of the symptoms are the same as otherwise reported here. Also, there are no longer published system requirements for MTGA on PC. It's been 2 weeks team, let's get this fixed. ............UPDATE, I tried the suggestion from https://feedback.wizards.com/users/6575812436-darkblack-38819 and changing the settings to Medium from Low seems to have stopped the crashes.

Updated Arena, now it freezes whenever I move the mouse cursor over anything that when highlighted grows larger visually.

All the same on Mac.

Relaunch from Epic games launcher solved the games issues, able to play again, but freezes in all the menus.

Settings --> Report a Bug --> Validate Bundles worked partially but The Shop was still freezing.

Setting the graphics to medium resolved the shop freezing.

Everything seems to work now.

(I don't understand the total lack of help from the support as we're so many experiencing the exactly same problem and clearly due to the update. There's need for a patch, reinstall or something like that. If someone obtain a technical support from them, tell us)

ATTENTION EVERYONE

Settings --> Report Bug --> Validate Bundles worked for me on 2022 M2 Macbook Air.

Try it!
