You can use processing algorithm "refactor fields" on the layer(s) that
have fields to be changed. This operation will give you a temporary
file/layer the same number of columns and -names as the original layer,
but with column type(s) redefined by you.
Afterwards you can merge the temporary file/layer with the other layers
Just be sure to have the latest (functioning) version of QGIS installed:
3.16.3. From the error message you included, I suspect you have an older
version of QGIS installed. I tried to merge 2 layers using QGIS 3.16.3
and the result was a new layer that contained the merged layers. If
there was a data discrepancy the result values were null's (but no
run-time errors)

Thanks Bo,
I tried a sample run but it failed:
"TAG field in layer Tree Table All 2 PntType has different data type
than in other layers (String instead of integer)
Execution failed after 1.20 seconds"
It looks like it can't handle differing data types and won't offer
choices for merging fields. I wonder if there are other tools?
Thanks again . . . .

Cheers, Spring
