JetBrains Toolbox won't open

Question

I use JetBrains Toolbox at work to manage my different projects and it has stopped working for a few days.

When I click on the icon, no windows open. Note that this is not the same problem as in this question, I just have nothing apparent happening at all.

---

What I've already tried:

• Restarting the computer
• Redownloading the toolbox from the official website and reinstalling

---

Additional info:

• I'm on Windows 10
• Options "Open" and "Settings" seem to do nothing.
• Option "Check for Updates" says I'm up-to-date
• Options "Show Log File in Explorer", "Send Feedback" and Version work as expected

Here is an excerpt from my log.txt (This may contain relevant info). Some file seems not to be found, could this be the source of the problem?

Answer 1

1. Add { "graphics_api": "Software" } to C:\Users\<username>\AppData\Local\JetBrains\Toolbox\.settings.json.

2. Add environment variable JETBRAINS_TOOLBOX_NO_SOFTWARE_OPEN_GL=true.

Answer 2

It appears this was a bug in version 1.11.4231 of the JetBrains Toolbox.

The bug has already been documented on YouTrack and solved in version 1.11.4269 of the Toolbox. A simple update solves the issue.
