Unhandled Exception after mdb Processing

Hi,

i do have a problem when I enable the mdb processing for my WebGrabPlus 5.3.0.0 on RedHat Linux 9.4 with mono 6.12.0.122.

I always get on the end of the processing the following error message and the new file is not created:

[  Info  ] Serie: 18686/18686 ..  Fußball: UEFA Champions League
[  Info  ]           Episode Name  : Paris Saint-Germain - Inter Mailand, Finale 2025 in Munchen
[  Debug ] "Fußball: UEFA Champions League" + "Paris Saint-Germain - Inter Mailand, Finale 2025 in München" + (2024) + "" .. no result!
[  Info  ] no result!

Without the mdb Processing it works flawless. Attached are all relevant files.
