Problem with CAN

[EPetr]

Hello! I use the BluePill Board. I have created a simple project VCP CDC, compile it, load it, plug the board into the computer everything is OK (file usb_cdc_1.zip). But if I add CAN to the project, the computer no longer detect VCP (usb_cdc_2 file.zip). Tell me what the problem is, what am I doing wrong?
