After upgrade from 4.5.0, cannot use SeleniumLibrary. Fails with error: TypeError: HybridCore.__init__() takes 2 positional arguments but 3 were given
Steps to reproduce the issue
Initial problem was found in Python 3.9, with upgrade from 4.5.0 to 6.1.1, and still happens in 6.6.1, also in Python 3.12.6. After downgrade to 4.5.0 in Python 3.12.6, test suite runs as expected.
On both IDEs, Visual Studio Code with Robotcode, and RIDE v2.1b1, the library is marked as failed to import documentation.

Expected behavior and actual behavior
Expected no errors and documentation loaded in IDEs and test run to proceed.
Environment
Browser: Chrome Browser driver: chromedriver Operating System: Windows 11 x64 Libraries
- Robot Framework: 7.1
- Selenium: ~~4.16.0~~ 4.25.0
- SeleniumLibrary: 6.1.1 and 6.6.1 (was OK in 4.5.0)
- Interpreter: Python 3.12.6
Hélio, does the error occur with the latest version of Selenium v4.25.0?
To me this is important as there is some version compatibility issues here. SeleniumLibrary only with the 6.6.1 release "officially" supported Python v3.12.x. And even there in that release we noted the Robot Framework v7.1 had not been released but we did test against 7.1rc2. But v6.6.1 suports only back to Selenium v4.21.0. (And only that far back because we weren;'t constantly testing/releasing each month during the summer as the most recent selenium version came out. Our goal is to support that last two seleniums).
So going back to either Selenium 4.16.0 or SeleniumLibrary 6.1.1 would be incompatable with Robot Framework 7.1 and Python 3.12.
@emanlove User says Selenium is 4.25.0. I'll edit version.
(I did upgrade on may machine too, but no problems. Maybe still some cache.):
No problems on my machine, after completely reinstall of SeleniumLibrary.
- Windows 10,
- Python 3.12.6,
- RF 7.1
- Selenium: 4.25.0
- SeleniumLibrary: 6.6.1
User reports that:
robotframework-seleniumlibrary 6.3.0. works fine.
@avnik User reports that upgrading pythollibcore did not solve issue:

@HelioGuilherme66 https://github.com/avnik/ghaf-ci-test-automation/blob/avnik/selenium/pkgs/robotframework-seleniumlibrary/default.nix package with robotframework-pythonlibcore from nixpkgs 24.05 works for me. Never tried to install in raw pip environment.
Closing this issue as unable to reproduce. It appears to be an incorrect version issue. Please reopen if more information arrises.
Just for anyone in the future, this was resolved for me by removing this library.
robotlibcore-temp 1.0.2
