We have encountered an NPSP Gift Entry issue related to the Spring '25 release where any checkbox field get a "value not of required type" error if they are unchecked when you try to save. You have to check and uncheck the box in order to save the record.
This has been seen in 2 different client orgs and in Sandboxes that are on the latest Release. It has been reported to Salesforce, but wanted to surface here for others as well.

We saw this happening with previously created and newly imported records. Here's the Known Issue article. Just sharing for anyone else coming across this! https://help.salesforce.com/s/articleView?id=004397650&type=1
