I’ve faced this issue after updating the UiPath Studio.
Please kindly help to support. thanks in advance.

JIT compilation is disabled for non-Legacy projects. ExpressionToCompile { ********
", ImportedNamespaces = System.Collections.Generic.HashSet1[System.String], VariableTypeGetter = System.Func2[System.String,System.Type], LambdaReturnType = System.String } should have been compiled by the Studio Compiler.

Dear,
Thanks for your feedback. I tried after updating it and also I did reinstall the UiPath Studio. but the issue is still there.

If you had your project updated by UiStudio, check all the syntax. Sometimes it’ll replace the double quotes wrongly, causing some issues. Mostly with strings.
