This error is driving me mad.
I was playing the game just fine till last night, suddenly today I get this error message every time I open the launcher.
Tried all the available solutions online: starting as administrator, adding files to exceptions in AntiVirus, deleting version files,
nothing worked.
It doesn't even let me install the files I deleted because every time I click on "Install" I get that error message right away.

what do I do?

P.S already restarted the pc several times.
