Hi @Michael_Chletsos

Please check the below thread:

Job stopped with an unexpected exit code: 0xC00000FD

One of my project which was working all fine suddenly faced this issue. On further investigation I found issue was at Read Range workbook activity. When replace that activity with Excel Application scope- issue disappeared. I have few other project on similar line which are not facing this issue where read range workbook. Even Config file used in framework is using Read Range workbook activity. 1 month back i faced this issue and it got resolved by EOD. This appears to be a bug

The Program show error unexpected exit code?

Hi @Bhargavi_Lokapur1 To troubleshoot and resolve this issue, you can try the following steps: Ensure that you have the latest version of UiPath Studio and the required packages installed. You can check for updates in the UiPath Studio by going to “Home” tab > “Updates” section. Check if there are any error messages or warnings displayed in the Output panel of UiPath Studio. These messages can provide additional information about the specific exception that occurred. Review your workflow and…

RPA Runtime error

Hmmm I’m not sure if the problem is not related to your IE. Please try the same with different browser.

Hey @Michael_Chletsos
Did you try this?

Error code 0xC00000FD

Error code 0xC00000FD can also occur in UiPath Studio when there is a stack overflow in the process being debugged. This can happen if the workflow is using too many recursive activities or if the workflow has a large number of variables and arguments that are being passed around. Try the following steps: Reduce the number of recursive activities: If your workflow is using recursive activities, try to reduce the number of times they are being called or find alternative ways to achieve the sam…

System.Exception: Job stopped with an unexpected exit code: 0xC00000FD

Here is the completed log I can see. System.Exception: Job stopped with an unexpected exit code: 0xC00000FD [image]
