Cubase 10.5.20 wont start since windows 20h2 update

my pc updated a few days ago to version 20h2 and now cubase 10.5.20 wont start.
it begins loading then as it gets to the initalize part it closes and wont get past it.
if i deactive all plugins and try and boot it it loads ok but i cant use any of my 3rd party plugins because there all deactivated.
ive not installed or updated any plugins and it worked fine up until the windows update.
can anyone help?thanks


To be it sounds one of your plug-ins in not compatible. Try to update all your plug-ins, please.
