ARCHICAD 23 crashes right after clicking Browse… button in the new Startup Dialog. Though, in general, other buttons like New… or Teamwork… work well and all projects can be opened from the File Explorer by double-clicking on them.
In some cases, accessing the content of a template file from a previous ARCHICAD version can fail. A template file is necessary for the Browse function to work. If accessing the template file is problematic the Browse function cannot continue and ARCHICAD crashes.
Re-save your template as an ARCHICAD 23 template file and make it the recent one as described below.
Open your template by double-clicking on it in the File Explorer and save it in ARCHICAD 23 as an ARCHICAD Project Template.
Open ARCHICAD 23 after it, click on New… button in the Startup Dialog and browse your re-saved template from the New Project dialog first dropdown. Open a new project using this template which makes it the recent one.
