Schematic difficulty with recent nightly builds: I tried all of this using general workflows which have worked well previously. I allow KiCad to save in new file formats as it seems to want to do:

I am using the following recent build to work on a schematic diagram:

Application: KiCad
Version: (5.99.0-1946-g60915fbc7), release build
Libraries:
wxWidgets 3.0.4
libcurl/7.66.0 OpenSSL/1.1.1d (Schannel) zlib/1.2.11 brotli/1.0.7 libidn2/2.2.0 libpsl/0.21.0 (+libidn2/2.1.1) nghttp2/1.39.2
Platform: Windows 8 (build 9200), 64-bit edition, 64 bit, Little endian, wxMSW
Build Info:
Build date: Jun 13 2020 21:04:17
wxWidgets: 3.0.4 (wchar_t,wx containers,compatible with 2.8)
Boost: 1.71.0
OCE: 6.9.1
Curl: 7.66.0
Compiler: GCC 9.2.0 with C++ ABI 1013

Build settings:
KICAD_SCRIPTING=ON
KICAD_SCRIPTING_MODULES=ON
KICAD_SCRIPTING_PYTHON3=OFF
KICAD_SCRIPTING_WXPYTHON=ON
KICAD_SCRIPTING_WXPYTHON_PHOENIX=OFF
KICAD_SCRIPTING_ACTION_MENU=ON
BUILD_GITHUB_PLUGIN=ON
KICAD_USE_OCE=ON
KICAD_SPICE=ON

I try to use the symbol editor to produce some power ports. (Same result later with schematic symbols.) To do this I open an existing power port, then “save as” and edit. Of course this does not yet save permanently into the symbol library. When I try to do that, KiCad repeatedly defaults to my project folder (not the different location of my library folder) but even after re-directing I cannot get it to really save.

I thought: OK; my build is a few days old so I tried updating to the latest I see which is
kicad-r16075.aeed8e6e2-x86_64-lite.exe

This latest build is much worse.

  1. If I open symbol editor from project manager, KiCad simply crashes (quits…goodbye).
  2. If I open an existing schematic diagram, KiCad freezes. (another crash). I tried two different schematics with the same result.
    I cannot do anything with this latest nightly build. Never encountered any KiCad build which is so malfunctional. I have now reverted to the previous build. I don’t want to experiment with one in between.

Now again with the previous build I can edit the schematic OK but I cannot save schematic symbols. But I do notice that KiCad seems to think that my KiCad symbol library (in my own folder) is read only. Can I fix this? As they have always been, my libraries are in my own folder, separate from the KiCad install folder and from my project folder. This has always worked well.

See https://gitlab.com/kicad/code/kicad/-/issues/4670. I have reported this without having seen your post.

EDIT: A fix for the crash will be available in the next nightly.

I infer that the behavior you observed was somewhat different from what I observed. I was completely unable to open a schematic (software froze partway) and completely unable to launch symbol editor (software immediately crashed-shut down.)
