I do sometimes re-install older versions when they start to misbehave.
Indeed, as far as I know, advanced users use several TC versions, there are good reasons for this.
We "buried" this problem a couple of years ago, but it as a zombie regularly rise from the grave

Yes, this ghost has an interesting psychological "feature" that allows him not to leave traces in bug reports.
Usually the user assumes that the problem lies in his current actions (habitual scenario), e.g.
- file open -> print
- file open -> open render manager
etc. or as in your case, installing the new soft / update.
That is, this bug is able to pretend to be other bugs. I'm sure he is responsible for most instant (non specific) crashes.
That's why I think that the new tool will be useful.
