After editing a new custom Task in ArcGIS Pro 2.6.2, saving and closing the project, my task has disappeared when reopening the project. It is still listed under Tasks in the catalog pane, but with a broken source exlamation mark.
Also in the project folder both the XML document and the ESRI Task File pertaining to my task have disappeared.
I was able to recover a .dat file from the C:\Users\xyz\AppData\Local\Temp\ArcGISProTemp22788 directory that has information and parameters on my task. See attachment.
Is there anyway I can convert this .dat file back into a Pro task? Saving it as a .esriTasks file dit not work unfortunately. I'm not looking forward to recreating the whole thing...
Any suggestions would be appreciated! Thanks.
