  --- BEGIN ISSUE ---
  `spyder-line-profiler` fails silently with latest 5.x due to missing import in `py3compat`
  <!--- **PLEASE READ:** When submitting here, please ensure you've completed the following checklist and checked the boxes to confirm. Issue reports without it may be closed. Thanks! --->
  
  ## Problem Description
  
  Running Spyder 5.x from `bootstrap.py` in an env with `spyder-line-profiler` 0.3.1 shows a traceback in the cmd/terminal from where Spyder was launched and the plugin doesn't load.
  
  Maybe related with https://github.com/spyder-ide/spyder/pull/20366 and probably also affects other external plugins which rely on the `py3compat` module
  
  ### What steps reproduce the problem?
  
  1. Install  `spyder-line-profiler` 0.3.1 
  2. Run Spyder from `bootstrap.py`
  
  ### What is the expected output? What do you see instead?
  
  The plugin to be able to load
  
  ### Paste Traceback/Error Below (if applicable)
  <!--- Copy from error dialog or View > Panes > Internal Console --->
