Are you able to click through the error and get Audacity to launch?
If so, please try this:
- Set up the “audacity.cfg.txt” as your audacity.cfg file
- Launch Audacity and click through the error screen(s) until Audacity launches.
- “View menu > Toolbars > Reset Toolbars”
- Close Audacity
- Restart Audacity
At step 5, does Audacity launch without error?
