    Take a look into the Crash log, browsing to the end of the log usually shows you the parts where it crashed, offers pointers, also check your editor output log for any red and or yellow warnings.

          Go to where your "Content", "Binaries" and "Intermediate" directories are located. You will see a "Saved" directory. In that will be a "Logs" and "Crashes" directory where you will find the logs you are looking for. I just have Notepad++ open to the my log file in "Logs" and refresh when I get crashes.

            UE4 4.23.0 doesn't delete hot reloading packages in [project]/Binaries/Win64. Not nice.

                  Sorry, I don't have time to file a proper bug report right now, so I'm dumping it here in case it interests someone. Found a few minor bugs within the Material Instance editor, 4.23.1:

                  1) Material Instance editor's Search doesn't search for some symbols in Parameter Groups names.

                  I only tested periods and round brackets ("." and ")" symbols), but I'm willing to guess it also applies to most of non-alphanumeric symbols (square brackets, underscores, etc.). The behavior only affects group names. Parameter names that use such symbols appear in the search results.

                  To quickly test, make an empty material with some parameters (use only alphanumeric names like "param1"), set them to a group called "1.Group". Make and open an instance. Search for "1." or "1.Group" (without quotation marks). The search will show no results.

                  2) Material Instance editor's "Show Child On Category Match" option doesn't seem to be working.
                  (This is way less important and not something I use, so I may be mistaken about the intended functionality here.)

                  To quickly test, make an empty material with a parameter called "Param" and set it to a group called "TestGroup". Make and open an instance. Search for "TestGroup". Both TestGroup and its Param parameter will show up in the search results regardless of the toggle state of "Show Child On Category Match" (found in the option menu in the upper right corner).

                    Apparently ARKit 3.0 (beta) failed to build on distribution. Runs fine on 4.23.0.

                      I have the exact same issue as drpsyko. Running 4.23.1, first time using unreal so no previous successful compilations

                      Comment


                        Setting from Project Settgins : Windows/ Default RHI = DX12, restart, then trying clicking FILE>PACKAGE> cause Crash to the Editor. Also 4.23.1 is by FAR THE MOST UNSTABLE ue4 version ever used. Many many memory leaks, ram goes up up just crazy, 4.23.0 was fine... what happend Epic ???

                          did you figure it out?... open the launcher, go to library tab... scroll down till you see the 8.23 launcher button... it should say 'update'... press

                          its about 3gigs for the update

                            And, I can confirm that resolution problem is not something specific to my project. Calling "r.SetRes 1920x1080f" console command in PlayerController within a blank C++ template 4.23.1 project causes crash in DX11, and forced window mode in DX12.
                            I answered this one above.
                            Its actually been resolved already here: https://issues.unrealengine.com/issue/UE-81742



                            Aside from that crash, this build is actually quite stable for me (wow), id suggest people post bugs to answer hub / make bug reports if they have crashes so epic can get this stuff fixed :-)

                            ->Edit:
                            I have tested and can confirm that small change fixes the issue. :-) superb!

                              There is some kind of major performance regression related to fairly large landscapes (4k x 4k in my case), particularly if they are in sublevels. I do not have all the steps to reproduce it yet, but at least in my own level, the delay between pressing "Play in Editor" and being able to play the level went up from about 0.3s in 4.22 to about 5s in 4.23. Also, if I move my landscape to the main level, the delay goes down to 1s, which is much more managable, but still significantly more than in 4.22.

                              If I create a blank project and create a large landscape and move it to a sublevel, the overall delays are lower, but it appears that they still have increased significantly compared to 4.22.

                              Has anyone else observed something like this, or knows of a fix or workaround?
