Ended up here due to the following error in QGIS 3.28.12 LTS and I was trying to export a layer in a particular format:
Invalid variant type for field geo_point_2d[35]: received QVariantMap with type
I was able to get past this error by scrolling through my table under the "Encoding" heading and check the Key/Value box and I was able to export my table into another format.
Inspired by this answer from user Timeless.
