I’m also having this issue. Has been since upgrading to studio version 2019.10.5

Anyone know what is causing this/a fix for this?

Any resolution on this?

Hi,

Nope not yet. I have raised it with UiPath technical support as I use enterprise edition of the software. Will update you if they get back to me with a response. Y

Hey guys! We are investigating this issue and will try to come up with a fix as soon as possible. I’ll keep you posted regarding the progress.

I also experienced this issue today (with studio 2019.10.4).

However, it somehow got fixed by enabling the ‘Official’ package source, in the packager manager.

We have found the problem and it will be addressed in a patch for Studio 19.10.

Please keep in mind that newer versions of Studio (20.4 and 20.10) do not manifest this problem.

Does this mean that the v20.10 System and UIAutomation packages are currently not backwards compatible with 2019.10 robot/studio?

Sorry for the late reply, I missed your post.

System is mostly compatible, I can’t think of anything that wouldn’t work in Studio 19.10.

UIA is not compatible because of the new features it has received (the “modern” behavior), without a specific connection to this topic. The classic functionality is still compatible. Maybe @gheorghestan can ellaborate on that.

UIA 20.10 is mostly compatible with Studio 19.10.x. Two new features - Modern recorder and Object Repository integration - require Studio 20.10.x
