Export fails when 'minify javascript and CSS' is ON - blank BSS window

Dear all,

Windows 10 Pro, BSS 4.5.1, trying to export my project. All export settings are ON except 'Use absolute path'. Export fails with a blank BSS window, no error message and no files in the Export Destination. When 'minify javascript and CSS' is OFF, the export completes without a problem. Anything I should consider when exporting, that could lead to such behavior? BTW: preview works.

I wanted to file this as a bug report as no error message is a bug to me ...

Best, Michael
