Lovelace becomes unresponsive every couple of days

Every couple of days lovelace becomes unresponsive and needs to be rebooted. I don’t see any errors that would indicate the problem though.

Some of the items in the sidebar will be missing the name and other names will be in all lowercase.

Here are some examples of the lovelace errors I am getting. It happened again this morning but I don’t know what time it happened. I copied the logs but I’m not sure if it is helpful.

Edit: I was able to find the logs from when I think the problem happened.
