I found a way how to fix that.

Webbot comes with its own webdriver, which is outdated, so you have to replace that with your own.

First, go to the directory where webbot's source code is stored. (Use webbot.__file__ to get the directory).

Then, open the drivers folder and replace chrome_mac/chrome_linux/chrome_windows.exe file with your own webdriver.

Now you also don't need to specify your webdriver's path in Browser().

This should solve your problem.

Note:—
You may also need to degrade your selenium version to 3.141.0 because it gives errors in some cases.
