Using QB Pro 2018.  Crashes immediately after startup, after I try to access reports.  Problem occurs with multiple company files.  Used Quickbooks Tool Hub to no avail.  Reinstalled QB Pro 2018 yesterday, using downloaded file from Intuit.  Updated to all maintenance fixes.  Worked yesterday after reinstalling but crashing again today.

I spent all day yesterday on this. QB support was worse than useless. 

The only solution is to uninstall and reinstall QB and NOT install any QB Updates. This resolved it for me.

As soon as I allowed the QB update to install, the problem returned and I had to repeat The process of uninstalling and reinstalling.
