Deeplearning validationData in 2021b (deep learning toolbox)

Hi i just installed the 2021b version, and now i cant use the combinedDatastore class as validation data, it works just fine in version 2021a.

When i try to run my code in 2021b i get the following error:

Error using trainNetwork (line 184)
Conversion to single from cell is not possible.

Caused by:
    Error using cast
    Conversion to single from cell is not possible.

Does anyone know what i need to change in order to get my code to run in 2021b?

best regards

yes，sir，may be upload some code or data，or use

A = cellfun(@single,your data) such as

A = cellfun(@single,{1,2})

to avoid data type transfer
