Thrown under the bus and need advice!

I’ve been working on a high stress project with a Director from a different department for about 2 months now. She is known to be challenging to work with, but up until this week I seemed to get along with her better than most people. My boss asked me to help with another urgent project that is due on Friday and I informed the Director that I would be less responsive than normal because of this other project. She said she completely understood. Hours later she emailed me asking for a status update on the project we were working on. I didn’t respond right away, but provided an update. Then later that afternoon she sends an urgent email saying that she needs me to compile some data for her by the end of the week. The next morning, I provide her with an update in an attempt to get ahead of any asks she may send my way. She again asks for multiple status updates as the day progresses. Then her boss emailed my boss and asked him to designate someone to provide them necessary support and that I need to send daily updates (which I had already been doing). That same day the Director emailed me and copied 10 other regional leaders, asking me to account for discrepancies in data she had received from her Regional leader. The implication was that it was my fault there was inconsistent data. I didn’t appreciate being thrown under the bus and in such a public way. I calmly responded that the data discrepancy was because her leader was using an outdated report. She emailed me separately, saying thanks. But never responded to the group. Ultimately after months of being super responsive to her, the moment I put some boundaries in place she went above me and threw me under the bus. I really don’t like confrontation and try to take the high road, but I am wondering if I need to address this with her? She’s in a more senior position than me so I’m not sure if this is a smart move. Should I just let it go and move on? Any advice would be much appreciated!
