I got above exception with EC2 server instance. My script works absolutely fine with Ubuntu and Mac os with any version of firefox and geckodriver on local system. But got above error with EC2 ubuntu 18.04.01 version, in this I have also tried upgrade and downgrade firefox and geckodriver versions but still not work. Can anyone help me out with suggestion and solutions.
                Are you sure that the application is launched and navigated to the page where you have the element with id FavoriteApp_ITEM?

Traceback (most recent call last):

selenium.common.exceptions.TimeoutException: Message: 
...implies that the WebDriver variant was unable to locate the desired WebElement within the timeframe for which the WebDriverWait was constructed.
WebDriverWait
The WebDriverWait constructor takes a WebDriver instance as an argument and timeout in seconds.
Hence, irrespective of usage of either of the expected_conditions, WebDriverWait on failure will result in TimeoutException.
This usecase
In this usecase, the line:
EC.element_to_be_clickable((By.ID, 'FavoriteApp_ITEM'))
was unable to identify the desired element within the desired time frame hence you faced TimeoutException.
However, from TimeoutException it will be tough to dig out the actual result of the failure.
Solution
As a solution to know about the exact cause of the failure, you need to remove the WebDriverWait and replace the line of code with either:
find_element_by_class_name(name)
find_element_by_css_selector(css_selector)
find_element_by_id(id)
find_element_by_link_text(link_text)
find_element_by_name(name)
find_element_by_partial_link_text(partial_link_text)
find_element_by_tag_name(tag_name)
find_element_by_xpath(xpath)
If required you can slow down the search inducing waits through time.sleep(secs) while debugging.
References
You can find a couple of relevant discussions in:
selenium.common.exceptions.TimeoutException while invoking .click() on an element through expected_conditions
ExpectedConditions.ElementIsVisible returns TimeoutException even when element is present
                Thanks @DebanjanB you are correct I have changed the script as per your suggestion it works
