UiPath Studio freezes when copying ANY content (activities,logs, text, variables, strings)

Hi everyone,

I’m experiencing a critical issue with UiPath Studio during development (not execution).

Issue description

UiPath Studio freezes whenever I try to copy anything, not just activities:

  • Activities (Ctrl+C)

  • Variables

  • Strings inside activities

  • Plain text (even from logs or error messages)

This is not related to running workflows. The issue happens while editing.

Behavior

  • Studio freezes immediately after pressing Ctrl+C

  • Sometimes it recovers after a few seconds, sometimes I need to force close

  • Happens consistently, regardless of project size

Environment

This seems related to clipboard interaction, since the issue happens even when copying simple text.

What I already tested

  • Restarted Studio and machine

  • Tested in a blank project (same issue)

  • Ran Studio as administrator

  • Disabled background apps

  • Cleared UiPath cache

  • Updated to latest version

Additional notes

  • The issue started: [after update / suddenly / unknown]

  • Happens every time I use Ctrl+C

  • Does NOT depend on project complexity

Question

Has anyone seen UiPath Studio freezing due to clipboard operations?

Could this be related to:

  • Windows clipboard history?

    • Never has been activated
  • Third-party clipboard tools?

    • Might be TightVNC?
  • Known Studio bug?

Any workaround or fix would help a lot.

Thanks!

Check your CPU utilization. If it’s high then this could be one of the reason behind it.
