I noticed a short while ago that Edge Canary had disappeared. So..... I reopened it and sure enough, a couple of minutes later it crashed. Did the cursory repair and still have the issue. Has anyone ...
since microsoft is slow fixing this i have found older version of edge canary (build 128.0.2688.0 ) extracted with nanazip, found inside another 7zip file and inside the proper working build, no crash running that.
