I have seen this on several devices and several versions of Android. This is what happens, while creating a location profile asa I reach the step to choose the area on the world map there is a high probability of Field Maps crashing. It can happen on any step after this, like choosing the transformation or naming the location profile. Workaround I found is to do it very quickly. If I am able to give it a name and save it and if FM still crashes, I can find the newly created location profile on restarting FM. If it crashes before I could save, then I have to create it again. Would be nice if this could be fixed.
Thanks
