Qt Creator closed because of a problem with the "CppTools" plugin

I upgraded Qt Creator from version 4.8.? to 4.12.0. Then, I added Qt 5.14.2 to my Qt installation. Now, I'm unable to load projects in Qt Creator at all. When I launch Qt Creator, I'm greeted with the following error window:

If I press "Continue", nothing happens. If I press "Disable Plugin", Qt Creator successfully launches. However, I'm unable to open any of my C++ projects because of the error: No plugin can open project type "text/plain".

I went to Help -> About Plugins..., and observed that the CppTools plugin is indeed force-disabled.

I don't know why there is a problem with the CppTools plugin, and I've run out of places to look. I am on Windows 10.

Hello,
I have exactly the same problem.
Actually no solution found.
I'm using QT on Windows 7.

I reinstalled Qt, and I'm still getting the same error regarding the CppTools plugin.

I have gotten around the issue. Someone logged this bug earlier today, which is related to user settings: https://bugreports.qt.io/browse/QTCREATORBUG-23916

I cleared my Qt Creator user settings folder, and then Qt Creator opened successfully. On Windows 10, the folder I cleared was: %APPDATA%\QtProject

Thanks, it works also for me.
On Windows 7, I cleared the folder "Users\UserName\AppData\Roaming\QtProject".

Thank you.
Here is the command for OSX (from default user path)
rm -rf .config/QtProject

Doesn't work at all. Just upgrades to Qt 5.14.2 -> problems with CppTools plugin

Hi @TomGerman,

https://bugreports.qt.io/browse/QTCREATORBUG-23916 contains a workaround and links to the planned Creator version 4.12.1 which fixed that crash.

Regards
