This error can occur with almost any program, not necessarily LO. Apparently an essential file in your LO installation is corrupt. Maybe it helps if you reset your user profile. See Frequently asked questions - General - The Document Foundation Wiki - important: rename the folder, don’t delete it.

I think this type of error occurs because of the outdated Windows 0S.
In order to fix soffice error 00000142, we need to update the OS as soon as possible.
