map devise problem

Hello, I'm having problems pressing my map device in LEAGUE and not in standard mode. In standard mode, everything works fine.
In league mode, however, I did a corrupted nexus on a tower in the endgame, but I didn't receive the atlas points I was supposed to. Frustrated, I quit the game.
When I reconnected a little later, I wanted to launch a small map on the map device, but as soon as I clicked on it, the game crashed.
I think it must be because I didn't get the atlas points and that it must have crashed there, but I don't know any more and I'm out of solutions.
I've already checked the integrity of the game files, uninstalled and reinstalled the game, and deleted the game caches, but nothing changes; it doesn't work. I play on PC and through the Steam client.

Thank you for your future response.
