After opening the "Conflict Processor" for a while, there was a crash and an error occurred

[ihhjnh]

After opening the "Conflict Processor" for a while, it crashed and popped up the following error. It seems to be a font issue, but no corresponding file causing the error was found in the local files. Could the master please take a look and help figure out how to solve it?

Hey,

I can see this is a very old Windows version, which is likely hitting legacy font-related issues. The error indicates that the system is unable to resolve a default system font, causing Avalonia to fail.

To work around this, please enable the option that forces Irony to use only its bundled fonts (Noto Sans and Noto Sans CJK).

Set the following value to true in appSettings.json and try again:

IronyModManager/src/IronyModManager/appSettings.json

Line 9 in 387cb78

"UseInbuiltFontsOnly": false

[ihhjnh]

I switched to a new computer and changed the "UseInbuiltFontsOnly" option in Notepad to "true". After saving and using it for about ten minutes, the program still crashed and produced an error.

Can you isolate which mod is causing it? Seems like it's using a character not found in the noto sans cjk map.
