hi [Mod] Kumasasa The other time my report was considered invalid because it did not understand my question.
I already reported this probrem before, pay attention this time.
view: https://bugs.mojang.com/browse/MCL-5361
This problem has to be with the launcher and not with minecraft.
I already tested with the old launcher and the current one, make sure it is not known and have an error with the new launcher.
All versions before 1.6.1 crash after loading on the mojang screen.
I'm sure it has already been tested in several versions, only the previous ones to 1.6.1 crash.
I personally kindly do not ignore the bug this time, for many minecraft users it is important to access old versions.
thanks for listening.

You're using an old version of Minecraft. We're currently accepting reports for the latest release 1.11.2 only.
(And no, it's very very likely not a launcher issue.)
Also:

This.
Edit: And you're using mods. Another reason why this is invalid.

It's still not a Launcher bug, it's old Minecraft crashing for some reason.
Maybe it's caused because the language code in newer versions is completely lowercased ("en_us") whereas in older versions the country part was uppercased ("en_US")
And still, anything below 1.11.2 is not supported here.

I never use mods.
Since me problem can not be solved I will have to use the previous version of launcher
The previous day of the update worked perfectly.
But anyway my problem continues, my only hope is to reinstall the minecraft or use the old launcher.
I'll let you know if it works.
Thank you for your prompt service.
sorry if I have been offensive.

Re-install minecraft works
Really was not the launcher, we will never know what caused it, but we will know that re-install cast.
Thank you for all your attention, patience and tolerance.
You guys are really professional [Mod] Kumasasa.
Really thank you.
Dude, don't spam your problem that only pro-longs it.
