Damn Conda morons. I have seen that before. It looks like they broke
Python 3.7.7 installation on RedHat 7.8. That is a linker problem you
see. I just checked and I can still load python 3.7.7. but when I run a
conda command I see the same error. We have 8 computing nodes in total
running RedHat 8.2 and they are not affected. Please try to rebuild your
environment and report. I will see later today if reinstalling can help.
I am a moron too. I was contaplanting upgrading Python to 3.8.3. I
should be much more careful with Conda guys. 

You also have RedHat rh-python36 in /opt/rh. That one always works.
