KeyError: 'pandas._libs.interval' MacBook Spyder 4.2.1

[Marije Bol]

I installed Spyder (version 4.2.1, Python 3.9.1) on my MacBook, but when I ran a code which includes pandas I got this error:

------------------------------------------------------------------------------------------------------------

During handling of the above exception, another exception occurred:

Does anyone know how to fix this pandas error?

Thanks in advance
