First I load it to bytes, then calls as follows.

return CryptographyProvider.Default.get(RSA.PKCS1)
    .publicKeyDecoder(SHA1)
    .decodeFromByteArray(RSA.PublicKey.Format.PEM, data)

It will be show following error messages.

Hey!
Thanks for the report, but I can't reproduce it at my side.
The following test finishes successfully:

val pem = """

""".trimIndent()

val key = CryptographyProvider.Default.get(RSA.PKCS1)
    .publicKeyDecoder(SHA1)
    .decodeFromByteArray(RSA.PublicKey.Format.PEM, pem.encodeToByteArray())

assertEquals(
    pem,
    key.encodeToByteArray(RSA.PublicKey.Format.PEM).decodeToString().trim()
)

Could you provide some kind of reproducer?
