I had a same problem but got it resolved within 5 months. what I did is I removed broken links from site. I checked inbound and outbound links of the site. I scanned the referring sites in a free virus dectector, I removed inbound and outbound links that were connecting to sites that might have malware. I removed extra local schema which was stuffed into blog posts by rank math. Also checked whether your hosting is blocking bingbot or ask Hosting Support to check if there is malware in site or hosting. After checking all these things, I contacted bing webmaster Support by registering a ticket. It took 5months but site got indexed.
