Error in QuestaSim when starting simulation

Hi, Every time that I open Questa and click on "Start Simulation" for the first time I get this error message!

I have tried figuring it out on my own but I really don't understand what's going on here. It doesn't seem to actually have any effect on my ability to simulate things but its annoying and makes me think there are more issues with my install.

Here is the stack trace

can't pack .main_pane.library.interior.cs.body.search_bar inside .dlg_sim_opts.top_row.child_f.nb.canvas.notebook.cs.page1.cs.libbrowser
while executing
"pack .main_pane.library.interior.cs.body.search_bar -side bottom -before .dlg_sim_opts.top_row.child_f.nb.canvas.notebook.cs.page1.cs.libbrowser.conte..."
("eval" body line 1)
invoked from within
"eval $d($w,show_cmd)"
(procedure "SearchBar::show" line 71)
invoked from within
"SearchBar::show .dlg_sim_opts.top_row.child_f.nb.canvas.notebook.cs.page1.cs.libbrowser.contents {}"
("after" script)

Thank you!

    Try suggestion below:

    1. Restart Questa with a Clean GUI Cache

    Sometimes, GUI settings get corrupted. Try resetting them:

    Close Questa.

    Locate the Questa preferences/settings file (usually in your home directory or workspace).

    Rename or delete the GUI-related cache/config files (e.g., .questasim or .modelsim folders).

    Restart Questa and check if the problem persists.


    2. Run Questa with a Fresh Workspace

    If this issue occurs in a specific workspace, try:

    Creating a new workspace.

    Importing your project files.

    Running the simulation again.


    3. Verify Your Installation

    If the issue is persistent across different projects:

    Make sure QuestaSim is installed correctly.

    If you’re using an older version, consider updating to the latest version.

    Try reinstalling or repairing your Questa installation.


    4. Check for Custom Tcl Scripts

    If you have custom Tcl scripts or configurations modifying the GUI, they might be interfering with the default behavior. To test:

    Run Questa without any custom startup scripts.

    Try launching the GUI with the -gui option:

    vsim -gui

    See if the issue still occurs.


    5. Disable Search Bar in the Simulation Options

    Since the error is related to SearchBar::show, disabling the library search bar (if possible) might be a workaround. Try:

    Going to Simulation Settings and disabling search-related features.

    Running the simulation from the command line instead of the GUI.
