XY Folder can't open resource (font)

[mbac]

Hi,

I'm running Comfy 0.2.7 on Ubuntu 22.04 (cloud server). At the end of a grid-from-list workflow I keep getting the following error:

# ComfyUI Error Report
## Error Details
- **Node ID:** 184
- **Node Type:** CR XY From Folder
- **Exception Type:** OSError
- **Exception Message:** cannot open resource
## Stack Trace

From the rest of the log (pastebin, as it's very long) I'd say it's a problem with fonts, but it's different from the one I've seen in prior issues.

Can anyone please suggest a workaround?

Thanks!
