@kozo2 Can you install devel branch and try it again?

[kozo2]

@yihangx I installed the devel branch and tried it, but unfortunately, the issue persists. Do you have any other suggestions?

[yihangx]

@kozo2 Could you try it again? It worked in my docker image.

@yihangx I tried it again (for RCy3_2.21.3.tar.gz). It worked also in my docker image.
