5E character sheet errors

[Mansquatch62]

Having issues with 5E throwing up several errors when characters are opened. Whenever the main tab of the character is opened it throws up errors. Also, the section containing Class and Level are blank.

This happens every time the main tab is selected.
The first time the Inventory tab is selected, the following wall of errors appears.

After the first time opening the inventory tab, these errors do not reappear.
These shots were taken running no extensions other than a theme.
I can send the compiled logs as well. Didn't know if those can be posted here or should be sent privately?
Thanks.

It sounds like something isn't up to date. What version of the 5e and core rules is noted in chat when you log into a campaign.

Make sure you have no folders or unpacked rulesets in your rulesets folder.

That was it! Thanks Zacchaeus. I had modified my CoreRPG.PAK in January to change some font colors for an oddly colored Expanse theme, and was copying it into the ruleset when I ran that game. I need to remember to save a copy of the current update version of CoreRPG.PAK.
