The Dev version of Edge crashes while I am using it. I uninstalled it and installed the Canary version. Is Microsoft aware of the bug?

Similar issue as previous commenter: however, my browser instantly crashes upon launching. I'm having to use a different browser to find solutions as Canary crashes maybe 1.5 seconds after launching it. No new extensions, downloads, or anything like that. Started on the 28th of this month. Really hoping for a solution/patch to this update if that is the root cause.

Version 124.0.2478.51 (Official build) (64-bit), "Print Preview" image for a PDF is shrunken now rather than normal page size!
