It looks related with aggressive antivirus or something like this, which is holding a lock on C:\Users\Patil\AppData\Local\Arduino15\package_index.json.tmp . Try pausing your antivirus while opening Board Manager to check if it gets fixed.

go into: C:\ProgramData\MATLAB\SupportPackages\R2018a\3P.instrset\arduinoide.instrset\idepkgs
and delete package files

@akshaymali046 we're still waiting for you to let us know if disabling the antivirus resolved this issue for you (or if there was some other resolution you found). Please take a minute to provide us with an update.
