Libre office calc Crashes frequently -Large files

Hi,

My Libre office Calc keeps crashing often while saving large files. Please suggest
what to be done to resolve this issue.

Version: 6.3.0.4 (x64)
PC version : Windows10

Regards,

First steps to take before submitting a bug

Try a newer version. Maybe it is a bug already fixed. If you wish to be careful, use the portable version, available for Windows for testing.
.
Provide more information please: You save as .ods or in xlsx flat-xml etc. ? Disk-space available? And what is “large”? (I remember a recent discussion, where the intermediate =not compressed data exceeded the 2GB, resulting in a file wich could not be loaded everywhere…)

Note that recently ZIP64 support was added - not sure it would fix that issue, whichever was that - but worth trying.
