NYS Labor Commissioner withdrawing my unemployment determination for further fact-finding - what happens next?

Just got a letter saying the Commissioner of Labor is withdrawing my determination(s) and will do more fact-finding. The exact wording states "The Commissioner of Labor is withdrawing the determination(s) in the above case. The Commissioner will conduct further fact-finding." The letter mentions that if a new determination is issued, it will be sent to me. It also says if I disagree with any new determination, I must make a new request for a hearing. For questions about the status of any hearing requested on the withdrawn determination(s), they told me to call the Telephone Claims Center at 1-888-209-8124. I've been trying this number repeatedly but haven't had any luck getting through to anyone. The form appears to be from the Unemployment Insurance Division with a form number of AB 664.1 (5/22). Anyone else dealt with this situation before? Not sure what this means for my unemployment benefits or how long this new investigation will take. I'm getting concerned about my payments potentially being interrupted while they do this additional fact-finding. Has anyone experienced this "withdrawal of determination" process and know approximately how long I should expect to wait?
