What does Error Code 402620403 mean

This Error just started today and the message does not have enough info to explain what is wrong. It is occurring with code that worked last week. It even occurs with code from new project unchanged. I can not find any data of this type of error. Code is on my iPad Pro 10.5 inch running iPadOS 14.2. It fails on both my Mac Pro and My MacBook Pro systems. I want to run on more that simulators. I have written software for over 50 years and this message has to little info to help if I can get only a code number.

thanks for any help
