Any reason to stick to Spyder 4.2.5 instead of using Spyder 6.0.0?

Hey @yangwencenc, thanks for reporting. This problem should be fixed in our latest version available in Anaconda (5.5.1). Please update by closing Spyder, opening the Anaconda Prompt and running there the commands mentioned in our documentation.
