Why I cannot do TIN Interpolation in QGIS?
It is because of some small lines that are in your file that cannot be handled by Interpolation. You can use Generalizer3 in QGIS plugins to remove those lines.
I want to do TIN Interpolation on a layer but when I fill all the fields with the right data (vector layer, interpolation attribute, extent etc) the algorithm does not run and shows me this message:
Traceback (most recent call last):
File "C:/PROGRA~1/QGIS 3.14/apps/qgis/./python/plugins\processing\algs\qgis\TinInterpolation.py", line 188, in processAlgorithm
writer.writeFile(feedback)
Exception: unknown

Does anybody have an idea about it?? Thank you
