I am running Robot Framework 5.0 (an upgrade from 4.x.), using PyCharm 2021.3.3 Community Edition. When I try to use a BuiltIn Library keyword it is not available. I have seen this behavior before with SeleniumLibrary but the cause was too many spaces between Library and SeleniumLibrary. Since you do not import BuiltIn I am confused on what could be the root cause.
I am inputting the Keyword into the Keyword section. For example none of the “Should Be Equal” keywords are found.
I do not have issues with other libraries: Selenium, String, or Collections:
