Game doesn't run under user account with exclamation marks / special characters

Please attach the complete output of the "Development console" of the launcher. CTRL-A, CTRL-C there, CTRL-V in the ticket.

C:\Users\Jasyn!!

Use a username without exclamation marks. This is a serious problem with pathnames and Java.

Thank you so much! you have the best thanks and reguards my good friend and also, happy new years!

Hello,

I tried creating a new account on my computer with no special characters in the name, just letters. I ran minecraft.exe and it gives me the same error as I talked about earlier.

Same thing happens when I try to change the directory that minecraft works in.

How do I fix this without having to create a secondary profile on my PC. The fact that I'm having this error because my main profile for the computer has an ! on the end of it is absolutely ridiculous.

Once I created the secondary profile it was fine and loaded like any normal program. But once I switched back after successfully having it load on the second computer profile, the main one still won't function correctly because of the "!" on the end.

Looking at the other people suffering from the same thing, they've also said removing any special characters from the names after the fact does not fix it.

(Edit) 1/25/2021

Going into my control panel to edit the user profile to something without the ! point on the end of it has not fixed the issue. My ticket was closed because it is saying it's a duplicate of this one.

Changing the account name does not fix the issue; the problem is the ! in the path which isn't changed when renaming your account. As the linked post says, you need to either change the game's work directory (so that Minecraft jars are not in a folder that has an ! in it), or create a new user account whose name does not have an !. The page seems to no longer have a link, but here are instructions on how to change the work directory.

The Minecraft launcher is not a .exe file

If you no longer wish to receive emails, click "stop watching this issue" near the top right of the report. People commenting on an issue that they are still running into is normal behavior, and 4 comments over over 4 years is not an excessive number.
