Datascan not picking up the schema of .parquet files ParquetFormat JavaInvocationException happened

Since about a week we have a problem with our datascan on ADLS not picking up the schema of .parquet files. It does pick up on the asset but not on the schema of said asset. The parquet files are perfectly readable and writeable with Fabric/spark. Purview had no issue picking them up before last week, but it seems that something has changed on the Microsoft side? Anyone else facing these issues recently?
