3.4.1 Upgrade error leading to recovery failure?

I upgraded from 3.3.? to 3.4.1 on a PC running Windows 11 Pro. After a problem mentioned below, I looked at a log from a fresh start of Audacity and find this:

==LOG follows

====END LOG

Does this indicate that the upgrade failed to load all the dll files properly?

I discovered this because immediately after the upgrade last night, I recorded successfully a 5 hour recording, but before I was able to save it this morning, Windows rebooted to install upgrades. When I then opened Audacity, there was no Automatic Crash Recovery window. When I went to the …Audacity\SessionData folder and tried to open (not import) the New Projectxxx.aup3unsaved file, I got an error message saying that “New Project …” is already open in another window", yet Task Manager shows only one instance of Audacity.

Next I opened the xxxx.aup3unsaved file in Notepad++ and found it full of NULL characters.

Any help in understanding this would be helpful. Do I need to completely uninstall Audacity and start a fresh installation, or what?

The log you posted says that you don’t have ffmpeg installed, and that you opened audacity with a blank project

Try using 3.4.2, it fixes a bug regarding crashes when opening projects with zero-length clips.

Thanks for that info. However, I continue to believe there was a problem in the installation of 3.4.2 over 3.3.? since it failed a couple of times because of crashpad_handler.exe. In any case, I thoroughly uninstalled 3.4.2, and after installing 3.3.2, all is well. I’ll wait a while before upgrading automatically again.
