Shiny App not launching after upgrading R/Rstudio and the packages

I have recently upgarded R/Rstudio and all the packages--

New R version 3.6.3
New R-studio Version 1.3.1093

My shiny app was working very well before the upgrade.Post upgrade the app does not launch and there is no explicit error in the logs.I extract the error from error part of inspect element>console .

Error: Syntax error: Unrecognised expression,#

Seems like jquery error.

Is this a bug?Nothing has changes in the code.
