Hello @venkateshgorantla

i can only suggest you that , create one more blank workflow , and just copy past the activity it will work

@Ajju it is very difficult to copy whole workflow i think need to create all variables. any other way?

No Worries
Kindly update all the packages in this xaml which could resolve this issue, by going to Design tab and manage packages option in that, update packages to the version of your studio or less than the studio version

Things to look out for if you’re migrating files from older to newer versions of UiPath missing packages uipath.core namespace genfour.activities namespace in the xaml replace <ua: tags with <ui: in the xaml check for encoding=“{x:null}” (usually in read/write csv activities) delete genfour.utitlies namespace (has an error sign) install v7 compatability resolve businessruleexception by adding the full path e.g. uipath.core.BusinessRuleException
