How do I correct LibreOffice from a crash

Prog simply crashed. When I start in safe mode I get 4 choices: Restore from backup, etc. I have tried each option & then click Apply Changes & Restart. When I click that nothing seems to happen. Then I cannot restart LO even in safe mode unless I reboot my computer. When I reboot & start in safe mode I get the same 4 choices. I did a System Restore (I am running W-7 64 bit) but that didn’t help. I would appreciate some help.

Reset your user profile.

LibreOffice profile is meant, naturally; not a system user profile.

Thanks for this clarification.

I asked the original question & had no confusion regarding the answer. It fixed my problem in a snap & made me realize how much I have to learn. Sincere thanks to the AskLibO team.
