After upgrade to version 12 start failing copy command on Linux: ScriptError: Failed to copy to clipboard!

After one of latest update copyq, start fails copy with "exit code 4".

Describe the bug I've made script based on example https://copyq.readthedocs.io/en/latest/command-examples.html#replace-all-occurrences-in-selected-text, that works fine more than year.

But recently start fails like:

Note: Exception in command "Keyboard layout change (xneur like)": ScriptError: Failed to copy to clipboard!
Note:    
Note:    --- backtrace ---

Note:    f@:1
Note:    eval:// Copy without changing...

1. Import example command https://copyq.readthedocs.io/en/latest/command-examples.html#replace-all-occurrences-in-selected-text
2. In editor select any text
3. Call command (by action or previously assigned shortcut)
