Cannot install the Guest Additions

[Goz97]

Hi,
I'm having a lot of trouble in understanding what the problem is with my Kali guest OS when trying to install the Guest Additions. I already upgraded the OS, installed the corresponding kernel modules, but whenever I try to install the GAs I obtain the following error:

"Cannot reload kernel modules: one or more module(s) is still in use"

I also attach the content of the /var/log/vboxadd-setup.log file, from which I cannot understand much (I suppose it has to do with the compilation of the kernel modules, but I cannot understand more)

What am I missing here? I apologize but I'm not that expert of Linux OS.
Thank you in advance.
