Opening Spreadsheet File Error

Hello, I am a new user of ONLYOFFICE Desktop Editors. It has been a nice change and alternative to Microsoft Excel. After downloading the newest version 8.3.2.19 (flatpak) through my Linux Software Store (my computer is running the AboveOS Linux system) I’ve attempted to open a large Excel spreadsheet (19.8 MiB) with several tabs and many pivots tables. However, each time, it gives me the error “We lost access to your file due to lack of memory or some other reason. Please don’t worry and try reopening the file. Close this tab to continue.” But, reattempting to open the file does not fix the issue.

Oddly, I have an older version of the ONLYOFFICE Desktop Editors 8.2.2.22 (deb) also installed on my computer, and it opens the speadsheet with NO issues, although it is very slow. Unfortunately, even in this older version it does NOT save the file after I click “save” under the file tab. Even if I try to “Save As” and rename the xlsx file, it will act as if nothing happened, and none of my changes will save, nor will it change the file name. The original file name remains.

I’m wondering if the spreadsheet is too large or complicated for ONLYOFFICE to modify? The version of Excel I was using previously to create/edit it was the newest from Microsoft 365, and I never had any issues with it.

I also had the same issue of not being able to open the excel spreadsheet in ONLYOFFICE in the latest version (8.3.2) on a different computer (Windows 11 OS).

Would greatly appreciate any insight or assistance! Thank you.
