Battleground

I had to uninstall the game and after reinstalling all the other modes work except Battleground... Unable to access Battleground the laptop screen remains frozen when I try to enter it

First, it is a good idea every few updates to do so, helps clear out leftover junk, and starts with fresh install.
Second, those that have to do so because of space constraints where downloading whole update could be as large as install itself, but having current install still on device doesn’t leave enough free space on device to do update.
Have you tried full uninstall again (including clearing cache), so long as you have login email/password remembered to be able to get back in your account afterwards. And re-installed from scratch a second time ???
Maybe your last install had some corrupted portion to it.
And besides that, BG is more intensive as far as maintaining a connection with game servers, that your device, load, etc, can severely be affected by.
Just like people eventually getting disconnects, etc, doing BG's. Maybe your's is too overloaded to even get to the point of trying to get thru BG in latest updates.
