You can apply for another US visa but it will also be sent to DS5535 admin processing. Note that DS5535 is issued against your name or profile and not your visa application. Hence, until the security clearance is received against your name from Washington DC, none of your US visa applications can be approved. Example: People who got DS5535 after the H1B visa interview tried applying for H4 and they again got the DS 5535. Ultimately, the visa was approved only after getting DS 5535 security clearance.
