Hi Bob! I posted a fatal error post, right before you. I also submitted a ticket and never heard back. The problem I am experiencing where it immediately crashes upon loading, makes Evernote literally useless for me.
I wanted to share, when I canceled my subscription (NOT closing my account, but canceling the renewal of my sub) there appeared an option to book a call with a support member. I have no idea if they offer this to everyone, or just to long time subscribers (I'm since 2012) but it's worth a shot!
I just completed the support call this morning with Alessandro and he was lovely and said he would try and have a tech person actually get back to me. I wish you luck!!
