I am using FMXLIVEGRID and every now and then my users get an livegrid evalerror in linkgridtodatasourceDB1 Access violation. access valu

I am using Delphi 10.3.3 on a PC 64 platform with tmslivegrid version 2.3.4.1
What can be causing this type of error, because if you close the app and go back in everything seem to be fine.
I need to narrow my search down with your help by showing me where this can happen.

Thanks

An eval error typically means there is a link to a field that contains content that is not compatible with the type it is linked to. For example, this could be a boolean connected to a string and in the conversion process the string is not recognized as a valid boolean.
