### Describe the bug
Reading Delta table with Comet enabled fails with the following error:
```
25/05/30 09:53:47 ERROR Executor: Exception in task 3.0 in stage 0.0 (TID 3)
org.apache.comet.CometNativeException: StructBuilder (Schema { fields:
[Field { name: "provider", data_type: Utf8, nullable: true, dict_id: 0,

### Steps to reproduce
The following PySpark code reproduces this issue locally.
```python
from pyspark.sql import SparkSession
COMET_JAR = "path/to/comet/jar"
spark = (SparkSession.builder
.master("local[*]")
.config("spark.jars", COMET_JAR)
.config("spark.jars.packages", "io.delta:delta-spark_2.12:3.3.1")
.config("spark.sql.extensions",
"io.delta.sql.DeltaSparkSessionExtension,org.apache.comet.CometSparkSessionExtensions")
.config("spark.sql.catalog.spark_catalog",
"org.apache.spark.sql.delta.catalog.DeltaCatalog")
.config("spark.driver.extraClassPath", COMET_JAR)
.config("spark.executor.extraClassPath", COMET_JAR)
.config("spark.shuffle.manager",
"org.apache.spark.sql.comet.execution.shuffle.CometShuffleManager")
.config("spark.comet.enabled", "true")
.config("spark.comet.exec.shuffle.enabled", "true")
.config("spark.comet.exec.shuffle.mode", "auto")
.config("spark.comet.exec.shuffle.fallbackToColumnar", "true")
.getOrCreate()
)
spark.range(0, 1000).write.format("delta").save("delta_table")
spark.read.format("delta").load("delta_table").show() # this line throws the
aforementioned exception.
```
### Expected behavior
Delta table should be read successfully.
### Additional context
Spark version: Spark 3.5.4
Comet version: commit
