All of a sudden, my Lazarus application is producing this error in Windows 10 when I try to run the executable which then does not appear. Previous versions do not trigger it. (The macOS, FreeBSD and Linux versions have no similar issue.)
The changes were pretty minor but extensive (added a file of device microprocessor defaults to be read; asterisk default values in combo box lists; remove asterisks when copying config options to clipboard etc, etc) and I suspect I'm going to have to go back and undo them one by one to find the issue.
In the meantime, does anyone have any ideas?
