As of today, I cannot connect to MetaMask any more from our site.
The chrome plugin gives the error (on any page):
TypeError: Cannot assign to read only property 'chainId' of object '#<l>'
And when trying to connect, it gives the error
TypeError: Cannot assign to read only property 'selectedAddress' of object '#<l>'
This started happen today, without any update on our part (and as stated, the errors appear on all pages, so seems to originate from the plugin itself).
I am using the Brave browser on Win 10.
I guess I just wanted to report this, but don’t know where.
Hi already reported the same issue (form post #22388) . And also chatted with the support, who alerted the developers about it. So lets hop it gets fixed soon.
By the way the problem seems to be Brave+MM related … in Chrome it worked for me.
Thanks for your reply, and good to know it’s reported.

Hello and welcome to the MetaMask community,
Please refer to the link above shared by @nakedwinnie and report the issue to the support team.
Can you try to go Brave Settings → Wallet and set your Default crypto wallet to NONE and let us know if it worked.
I just had the same issue and I managed to fix it, found the solution on github (I will post a screenshot since I cannot post the link).
