Confirmed this can now be self corrected -
The answer changed with SECURE 2.0 and Notice 2023-43. Specifically, Section 305(b) of SECURE 2.0 allows participant loan failures to be self-corrected under the rules of EPCRS section 6.07. The Notice, at Q&A 3, confirms that errors such as this can now be self-corrected, whereas before they could only be corrected under VCP.
