There is a #bug in Inkscape 1.2 that could destroy gradients, clips/masks, symbols, swatches & clones in a drawing.
You'll only notice it happened after saving file & later opening it again.
To work around this bug DO NOT use copy-paste while the Export dialog is open!
For more details on the bug, head here: https://gitlab.com/inkscape/inkscape/-/issues/3600
The bug will be fixed in Inkscape 1.2.1 (a fix is already available in the development ('master') branch).
