I can confirm the same behaviour described by gecko (Windows 10 v1809, Blender 2.90, LuxCore 2.5 alpha as of commit 9a0caab from 2 days ago).
It happens with all binary exports, either with Blender language set to "English" or to "Automatic".
Also modifying decimal and thousand separator in Windows control panel does not change the behaviour (I have Italian settings in Windows, but I manually set decimal separator to point and thousand separator to comma - the standard Italian setting is problematic for me with some other software. Both settings show the problem).
The error messages look identical to those described in this old issue (which was Linux-specific by the way):
https://github.com/LuxCoreRender/LuxCore/issues/80
The problem is also present when using Blender 2.83.5, while exporting with Blender 2.82 seems to solve it (same identical BlendLuxCore version in all Blender versions).
More specifically, when using the bcf exported from Blender 2.82, the render process starts without problems. At the moment of clicking "Finish job" on PyLuxCoreTool NetConsole, this error is triggered (which seems to me unrelated to the one in this thread):
