Hi Baptiste,
Thank you for sharing the information.
13.0.14.1720 tells us that the Service Pack is 14. So is your Visual Studio version VS 2015 RC (Release Candidate)?
With Visual Studio 2015 only SP15 and SP16 are supported.
Please go through the below link:
SAP Crystal Reports, developer version for Microsoft Visual Studio: Updates & Runtime Downloads
Keeping Crystal Reports tab out of picture for now, are you experiencing the same issue following the same workflow (with other tabs)?
Regards,
Vinit
