"An unexpected error has occurred while loading the application plug-ins"

Hello,

After updating yesterday the Analizer plugin, I am getting this error "An unexpected error has occurred while loading the application plug-ins" when opening SDL Trados Studio.

I visited the article from the Knowledge base "Article Number:000014282 |Last Updated:12/14/2020 2:38 PM" and have done the recommended steps:

rename or delete the plugin folder but I still get the same error.

I a running SDL Trados Studio 2021 SR1 - 16.1.5.4270 on Windows 10 Professional 19042.928.

Thank you in advance for your help.

Best regards,

Pierre Souchar
