Lot many issues after upgrading to 6.1.5 & 6.1.6

We recently upgraded Libre to 6.1.5 & 6.1.6. After the upgrade we are unable to access any files, the files are getting loaded very slow & at times it freezes the data not to load. Can someone help me in fixing this issue as there is a huge dependency on Libre office.

Which OS do you use?

We have Windows 7 & 10 OS at office and we are facing issues on both OS.

Please take a look at this FAQ from @mikekaganski. If there is no solution for you, you may want to return to an earlier version of LibreOffice. You can also give up your problem as a bug.

I’m afraid that the issue here is not an installation issue, but some kind of performance.

Yes it’s not an installation issue, it’s all about the performance.

Can some one help to fix this performance issue.

If it went better in an earlier version, I would go back there. Otherwise, probably only helps a new PC (?).
