I think this question is a duplicate of https://ask.wireshark.org/question/29..., and my answer to this one is the same as for that one:
I've finally gotten to the bottom of why this happens, at least in my case, but I suspect a similar situation is affecting you as well.
Basically, my company employs a tool that automatically updates a bunch of software, and Wireshark is included in the list of software that gets automatically updated. This is fine for a stock Wireshark installation, but not for a customized Wireshark installation. I am currently trying to work with our IT team to devise a solution to avoid having the customized version of Wireshark automatically updated. You will surely need to do the same if this is indeed the same thing that's happening in your case.
Please add the output of
wireshark -v

contents.I suspect this might be a duplicate of https://ask.wireshark.org/question/29... though, for which there is currently no solution, unfortunately, and something that has also plagued me for some time.

Yup, so you're also running on Windows. If/when you ever find an answer and resolution to this problem, I would love to know what it is too!
