Installing finplot i had the following errors.
"Spyder 4.2.5 requires pyqtwebengine<5.13 which is not installed"
"Spyder 4.2.5 requires pyqt<5.13 but you have pyqt 5.15.6 which is incompatible"
"Warning: the scripts pylupdate5.exe, pyrcc5.exe and pyuic5.exe are installed in \Users\Paolo\AppData\Roaming\.......\Scripts which is not on PATH. Consider adding this directory on PATH or if you prefer to suppress this warning use -no-warn-script-location.
After that Anaconda Navigator was not launching any more. I had to uninstall Qt5 and install again anaconda. What should I do?
