Of course they don't answer. They don't even test the applications. Just let us work for them for free ay

Right, because the forums is absolutely filled with this exact issue. I looked through the discord, we have exactly 10+8 messages which cover the two errors present, all are for different things, all were fixed by restarting the launcher once, twice or thrice, with the exception of a bug fix for something related but unrelated to this back in 2021. So yes, we don't test for edge cases that are 1 in a 10 million chance of happening.
