Building a custom Linux kernel causes VMware Tools to stop working

I am compiling kernels for CentOS 6.10 in VMware Workstation. For some reason when I compile and boot a new kernel, VMware Tools stops working, or at least the shared folders feature does, which is the feature I am using to copy files between the VM and host machine. CentOS is updated to the most recent updated kernel, which I am also compiling with rpmbuild as stock with no modifications other than defining buildid in kernel.spec to differentiate it. I am installing the kernel RPM as well as the kernel-firmware RPM. The kernel boots perfectly fine and everything appears to work other than VMware Tools. Does anyone know why VMware Tools stops working when building a custom (unmodified) stock kernel? I have tried reinstalling VMware Tools. This makes no difference unless I am on some version of a stock kernel.
