Hi, I downloaded the src for emacs latest (28.0.50) and built it. I also downloaded tramp elpa 2.5.1.2 and compiled it. With this combination I do not see the problem with the specific file I was having trouble with. Earlier, I was seeing an occasional crash of emacs with tramp (in addition to the above issue). I will continue to test with this new version in debugger to see if it crashes and get the backtrace if and when it does. Thank you.
