Blender Version
Broken: 4.0 and latest 4.1 build (November 15, 03:36:52)
Worked: 3.65LTS and 3.66 (now I put this version so I can continue to work)
Short description of error
If open any blend file made previous week/month/year -> Blender loads the splashscreen and then closes.
If I open a file made in 2022 or older -> that somehow works...
Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).
I double click on a .blend file
In less than 1 seconds: Blender will flash and be gone
On MacOS I get the: Blender quit unexpectedly
On Windows nothing happens.
I share report on Windows and a random blender project file that I was working on previous week.
This is the same bug, on Mac OS Sonoma
Hi, can confirm the crash. Versioning code where crash occurred was added in
16e4eeb9c0Simple null check will fix this, checking.
just tested the latest 4.0.1 release candidate -> same error like 4.0.0 (macos and windows)
Crash is occurring due to
Titlu articoltext object.Even in 3.6, crash triggered due to invalid string when switched to edit mode.
I wonder why
strinfois null and char buffer has invalid stringFor me in 3.6.6 and 3.6.5 LTS both titles (text and mesh) work and no crash.
@MiDe , could you check
030 O Muino card-simplified.blendfile (uploaded in last comment)? Switching to edit mode triggered the crash.Yes you are right but I am failing to understand why it matters :)
However, the file I shared (me) is not generating crash or ... anything. It just works in 3.6.5LTS and 3.6.6 :) MACOS Sonoma (and previous) and WINDOWS 11.
@lichtwerk ^
Possibly the text object data is corrupted. Or maybe it was created in quite old version
I do see some NULL checks on
strinfo(some with commenting "old file"), so a similar check might make sense.However, I do get the crash going to editmode in 3.6 as well, so there is definitely something wrong/corrupted with
Titlu articol.We should still be able to open these files I guess, will take over and make a PR for this.
@MiDe : you were mentioning other files that crash as well, mind sharing another one of those?
So the solution for this ticket is to fix 3.6.6 files so they can be opened by 4.0.0?
Yes, #114916 will add a workaround in versioning code so file can be opened in 4.0
But the "crash in edit mode" will persist in 4.0
OK thank you.
Personally I modified all my 32 projects (searched for those empty objects).
The problem is that I still wonder how did they appear... I saw one file and it had like 3 empty TEXT objects.
Way of Working: I made a master template (borders, stars, title, map) and kept just changing the central area only and saving the new project (all are here, www.europeoncamera.com). So I really don't know how by editing a text, sometimes it made a clone and that clone was empty. Maybe I pressed a command that I don't know and it made just a ghost of the text.
This is the master file that dates to 2022, last modified February 23.
Thank you Pratik B. & Philipp O.
I think this might give us a hint:
We dont have a font set here (this should not happen I believe, trying to find out why this can happen)
578b479998fixed the crash, will reopen the report though to investigate further how we can ever get an unset font hereBlender fails to open several projects done on 3.4/3.5/3.6 versionsto Text object can have an unset font (leading to crash in editmode)Crash persists after selecting font in an empty slot 😅
Yep, could be that we are already in a dead end when this happened (and are unable to recover...)
Also weird that - when loading a local font - it is marked as packed?
Stepping down since I currently do not plan on actually working on this
