Unable to load XML file in NI-MAX for Allied Vision Manta_G 145B. IMAQdx v. 20.6 and 21.0

I try to migrate from LV2014 to LV2020. If I try to open Allied Vision Manta_G 145B camera in NI-MAX i get Error 0xBFF6901D "unable to load xml file". IMAQdx Version is 20.6 (RT + Dev). Basler Cameras work fine.
I have upgrated the firmware of the cam to the newest version, but it didn't help.

I have also installed IMAQdx 21.0, but without success. A Manta-032B works without problems...

Any help or workaround is most welcome. Is there any way to load the XML file manually?

Finally, I was able to solve the problem. I do not know which of the two steps led to success:

1. I renamed in folder C:\Users\Public\Documents\National Instruments\NI-IMAQdx\Data\XML the file avt_E0020006_1.44.xml.
2. I copied the content of the folder PreProcessedCache from an IMAQdx 14.0 PC to the target PC.

Now NI-Max can open the cameras. The XML file has been recreated.
