Seeing very similar errors almost every play session. Sometimes crashes when queueing, sometimes crashes when clicking any tab on the home screen. Crash report usually contains a message similar to the one posted by vincent404 below: "error for object 0x<somehex>: pointer being freed was not allocated". Have tried updated to latest client version and tried uninstalling and reinstalling client, but neither seemed to have any effect.

I'm also getting frequent crashing, usually after launch when either clicking the deck or store tab. While the client will relaunch fine usually after the initial crash, looking the recent crash reports, I get a similar errors as well of the following:

System Integrity Protection: enabled

Crashed Thread: 33 UnityGfxDeviceWorker

Exception Type: EXC_CRASH (SIGABRT)
Exception Codes: 0x0000000000000000, 0x0000000000000000
Exception Note: EXC_CORPSE_NOTIFY

Application Specific Information:
abort() called
MTGA(23909,0x70000658b000) malloc: *** error for object 0x197600020: pointer being freed was not allocated

I can't quite track it down and don't know if it helps in reproducing it, but I have noticed just recently it may happen when I have a web browser open (either chrome or safari). That may just be a coincidence as I just reproduced the crash while typing this post.

Sometimes Arena gets into a state where I launch it, click "Decks," and then it crashes. This happens over and over again. I will try to attach logs.

I'm experiencing this issue as well.

Hello,

It sounds like you may need some more troubleshooting advice, please submit at: https://mtgarena-support.wizards.com/hc/en-us/requests/new and select 'Technical Troubleshooting'.

Thanks!

Same thing happens to me.
Game crashes every time I try to start a match, it's frustrating.

I got a report this time Arena crashed - I've attached it as a text file.

The Mac client from Epic Games crashes between nearly every match, typically when queuing for my next match.

Ok, it looks like the problem happens when I attach log files. I tried attaching just one smaller log file and it looks like I was still unable to post that comment.

That worked! I'll try posting a comment with one log file attached.

I've been trying to post a comment on this issue. This is my third attempt. I've been experiencing crashes at scene changes. I'm not going to try to attach log files this time, we'll see if that helps my comment get posted.
