Magic: The Gathering Arena, also known as MTG Arena, is the digital adaptation of the hugely popular card game Magic: The Gathering (MTG).

It’s a rather new-comer to the digital world; the beta version of thegamewas launched in 2017, and the final version for Windows users was released at the end of 2019.

Ever since the launch of the repeated testings, users complained about a recurring error. Namely, after each update, when they were trying to run thegamethey got aninvalid command lineerror.

The publisher, Wizards of the Coast (WotC), acknowledged theerrorand launched patches that were supposed to fix the problems. However, they still persist.
