Couldn't load plugin 'go2mapillary' due to an error when calling its classFactory() method

[joaourbano]

Hi,

I am currently trying to run the go2mapillary plugin on QGIS 3.4.14 Madeira on Mac OS Big Sur 11.2.1.

I am getting the following error:

Couldn't load plugin 'go2mapillary' due to an error when calling its classFactory() method

OSError: Could not find lib c or load any of its variants [].
