Geia sou Giorgo,

It looks like you need to blacklist some modules.

First create the following file (copy past from sudo all the way to last EOF)

sudo tee /etc/modprobe.d/exclusions-rtl2832.conf <<EOF
# Blacklist host from loading modules for RTL-SDRs to ensure they
# are left available for the Docker guest.

blacklist dvb_core
blacklist dvb_usb_rtl2832u
blacklist dvb_usb_rtl28xxu
blacklist dvb_usb_v2
blacklist r820t
blacklist rtl2830
blacklist rtl2832
blacklist rtl2832_sdr
blacklist rtl2838

install dvb_core /bin/false
install dvb_usb_rtl2832u /bin/false
install dvb_usb_rtl28xxu /bin/false
install dvb_usb_v2 /bin/false
install r820t /bin/false
install rtl2830 /bin/false
install rtl2832 /bin/false
install rtl2832_sdr /bin/false
install rtl2838 /bin/false
EOF

Then do also the following

sudo modprobe -r dvb_core
sudo modprobe -r dvb_usb_rtl2832u
sudo modprobe -r dvb_usb_rtl28xxu
sudo modprobe -r dvb_usb_v2
sudo modprobe -r r820t
sudo modprobe -r rtl2830
sudo modprobe -r rtl2832
sudo modprobe -r rtl2832_sdr
sudo modprobe -r rtl2838

then..
sudo depmod -a

After that I would reboot the raspi and hopefully all will be ok.
