Given that there are not numerous reports of such here in the forums, the problem is most likely something local to your computer, rather than with Scrivener.
As for Scrivener itself… Uninstall, re-download it, reinstall it and see if that helps.
If you created and worked on a Scrivener project on a previous day, it likely still exists… Try using File Explorer to search for folder names ending in .scriv and/or file names ending in .scrivx
Some anti-virus/anti-malware software such as BitDefender doesn’t like and messes with Scrivener. You may need to turn such off during download and install.
You may need to try alternate anti-virus/anti-malware software. A good one that you can try is Malwarebytes AntiMalware at malwarebytes.org None of them are 100% perfect??? but that’s the fallback tool I used in my work.
Beyond that, there’s a number of possibilities centering on the computer and software on it…
What other software is running?
How much RAM (chip memory) is on the PC?
Version of Windows?
How much free space on system drive (typically C: )?
If your computer manufacturer offers a systems diagnostic utility (already installed or available on their download site), use it to check your computer’s hard drive, RAM (chip memory), etc. the manufacturer of the hard drive in your computer may also offer a hard drive diagnostics utility.
If not, or to supplement/double check that, do the following things.
Run an integrity check on the file system on the system drive. In the old days, that was done via the CHKDSK utility. Now days… I’m drawing a blank… Right click on C: drive and see if something is offered there… perhaps in Properties. Or look in Control Panel. A Google search on “Windows drive check” or some such should turn up an answer.
Run a RAM (chip memory) test. If you are game to create a bootable CD/DVD or USB, search for, download, set up and use MemTest86 or MemTest86+.
Hope that helps. Post back here to let folks know how it goes.
