I was just on yesterday, playing away just fine, today, this new patch rolls out, I let the launcher attempt it's download and went to read the patch notes. Mid-way through, my computer locks up fully. Total freeze. I reset it all, tried again. Freeze solid again. I paid attention this time : When the launcher gets to 51% it hard locks/freezes my computer. Was working just fine before this, so I'm not sure what your program is doing, but something it's doing is causing a hard PC lock up/freeze. (As in, not even a cntrl alt del to processes or anything...it's solid locking it like a brick. And my computer is not exactly 'top of the line' anymore (It's 16 years old) but it's also been working just fine up to this point with the game. I tried updating the patch repeatedly an got the same outcome like 9 times in a row. Your launcher is getting to 51%, with 6.66 gb remaining, then is locking solid an forcing a off button restart of the PC with no other way out of it.
What's the solution other than 'turn it off an back on again' which I did each of those times?
