I am in such a phase as I write this. What should have been a week-long project has already gone through three and not finished. This is a simple multi-platform app I am building in Flutter.

One challenge I face is to be able to build something useful within a week. In two projects, I could make wirhin two days each.

For the Flutter one mentioned above, it took me two-three days just to get the tooling/SDKs to work and get me to a hello-world program working on Windows. Then it took about a week to program with all features I needed.

And then, damned again -- Took me a couple days to get it to build APK (random errors; the issue in the build tooling is still open). And then a week of craziness to sort out Android permissions. I still have the latter unresolved.
