Bitcoin core - node question

I’ve been running a full node on my computer for a year or so. After a while, the app seems to “close” and when I try to open it again or check the connections/data throughout I get this pop up..

Does anyone else have this happen? I can open task manager and see that yes the bitcoin core software is running but I can’t really verify it’s WORKING. Any input would be appreciated! Thanks fam.

PS if you’re not running a node, it’s super easy! Just pickup a 1TB hard drive or flash drive and download bitcoin core. Help secure the network and increase decentralization.
