EDIT: I uninstalled and reinstalled Word as an older version (16.84) and Word works perfectly well.
I have an Apple MacBook Pro M1 chip from late 2020. It works perfectly well. However, Word starts lagging when I use it for a few minutes. This is not an issue with my computer – all other programmes work perfectly well while Word is lagging.
I tried uninstalling Word and reinstalling it, but this problem has persisted. I have closed all other apps bar Word, but Word still lags. I have also tried moving documents out of my OneDrive folder so they weren't being autosaved onto the cloud, but the lag persisted. Running Activity Monitor on Mac does not show excessive strain on Memory, CPU etc. from Word.
I recently installed an update, and I wonder whether this is the cause? Stumped as to how to fix this issue.
