Home Assistant Node-RED Crashed out of the blue

Can anyone tell me what is going on in the error log below? This just recently started happening and I uninstall/reinstall node-red and add my flows back one at a time. So far, I can’t pin it on any one flow/node, but I’m leaning towards node-red-contrib-alexa-remote2, but I’ve had it installed and working for months, maybe a year.

Any help would be much appreciated!
