skinpack does not open

clicking + in the skinpack does not open anything
reinstalled the game, the problem disappeared, but not for long
problem since version 1.21.30
My friend and I use skinpacks, she has the same problem, but skinpacks from the marketplace also do not work correctly.
looked on the Internet, changed format_version 1 to 2 did not help, I do not think that the problem is in my skinpack, because some skinpacks from the marketplace also do not open
