🔍 Why This Happens

• The first main reason why this error happens in detail is due to a missing or corrupted font configuration file. The QtXcbQpa library relies on the Fontconfig system to manage fonts, and if this system is not properly configured or if there are issues with the font files themselves, it can lead to errors like the one described.
