Clion 2026.1 startup failure - Kotlinx.coroutines.CompletionHandlerException
已回答
Hi,
Have been using Clion 2026.1 on Windows 11 for several months and now I'm getting most of the time the following stack trace on startup:
I then Reset Settings & Plugins, it then asks me to import settings from Clion 2025.3 etc which I do. It then goes off and detects the MingGW toolchain and eventually lets me open a project.
This has happened 3+ times in the last few days and is really annoying, I have been really impressed with Clion up until this problem.
Can you advise please?
Regards
Gary

Hello,
The reported issue is related to the known bug:
CPP-49535 Do not access Dispatchers.EDT during application loading in `com.intellij.clion.radler.core.loader.RadInitialConfigurator`
It has been fixed in CLion 2026.1.1.
Please update CLion to the latest version.
Thanks, have downloaded the latest version. All seems to be OK again.
