I would recommend using Google Chrome for chess.com. I think it works best on this server.
Also, Chess.com is experiencing a large uptick in new chess.com members, and servers were not equipped to handle this many members. This results in pages occasionally crashing. Sorry for the inconvenience; staff has brought on reinforcements to code and are trying to get this fixed ASAP!!
My chess.com tab keeps crashing with an "Error code: STATUS_ACCESS_VIOLATION". The tab reloads and works again for 30-60 seconds before crashing again.
Using the latest version of Edge, tried both normal and incognito with no extensions, same thing.
