Hi, @copy_writes , Try go to Home → Setting → Reset Settings. After that restrat UiPath. You can also try restarting your machine if the previous step does not work.

@copy_writes

If that workaround mentioned above doesn’t work, could you please send me an output of the image via a private message @loginerror?

We will investigate the issue further.

Thank you for providing the details. Our team was able to look into the issue and is working on a fix that will be released with the next version.
