This bug was filed from the crash reporting server and is br-c3aa3d2e-61f9-433d-b485-a43ccd11ff8b. ========================================= 7.1.4.2 Calc crashes on closing. No query about saving file. Display remains on screen. Restart offers to recover file. OS is WIN 10 with current updates (09July2021). LO was removed from the system and reinstalled; no help. Tried rolling back (uninstall and fresh install) from 7.1.4.2 to 7.0.4.2. That works properly at least sometimes.
Could you give a try at https://wiki.documentfoundation.org/QA/FirstSteps ?
Let's see if a duplicate of Bug 141769 - fixed in 7.1.5.
Until final 7.1.5.2 is out may try 7.1.5.1 from Libreoffice.org Downloads Pre-release section.
Indeed, 7.1.5.1 resolves all of the crash issues I have reported here. Thank you.
Thanks for feedback, let's mark duplicate. Of course, you may take 7.1.5.2 when it's ready. *** This bug has been marked as a duplicate of bug 141769 ***
