Description

After functioning for a while, QGIS got into a state where it crashes any time the field calculator is used in the attribute table. The crash occurs immediately when the toolbar button (or ctrl+I) is pressed.

Removing python code from the default module in AppData/QGIS/QGIS3/profiles/default/python/expressions did not help.

Will do. Obviously it will function again as it did upon a clean install, at least for a while.

don't install any 3rd party plugins. If you do check if the FC stops to work after installing one of them, if it does then report it to the plugin author.

#4 Updated by Reino Ruusu about 1 year ago

Creating a new user profile in 3.4.3 was sufficient to eliminate the issue.

#5 Updated by Reino Ruusu about 1 year ago

Non-working fix attempts:
  • Replacing the .ini file in profiles/default/QGIS with a copy from a new profile.
  • Replacing the .db files in the profile with copies from a new profile.
  • Deleting the cache directory in the profile.
