I received an error message on a MIP1 result that was turned in.
(unknown error) - exit code -1073741819 (0xc0000005)</message>

However Windows 10 Pro registered the problem as an application error within the BOINC Agent as follows:

Additional data is available but I find no designated forum or HELP options to report such errors. Rather FORUMS seem to reflect a question/answer narrative format and I don't see Windows Applications Issues and I have not joined the BOINC Forum.
