Describe the bug

I couldn't sync my file with google drive because it has been deleted on google drive from unknow reasons.
But I had this file somewhere on my computer because I open it every day from keeweb with the "load from google drive symbol." This is a strange behavior for a file that was no longer on google drive since days or weeks.
So when I understood there was no sync anymore, I tried the "save to google drive option", in the hope that keeweb will save and sync a new file to google drive. Google drive open and ask my ID. Once done, nothing happen. no new file in google drive.
So, starting to worry, I choose to save the file localy, with the button "save to file" from keeweb. But no option displayed to save locally in simple .kdbx file.
And the "save" button (I don't really know what is its behavior) just do nothing. or maybe its save a file somewhere but no path is shown.
So I choose to make a backup. (not clear what is the diff with a normal file and a backup file).
Then I restart all clean. I delete all keeweb related thing on my computer exept the backup file, that I open with a fresh istall.
Since I don't quite understand the difference with normal .kdbx and .bak, I choose to re save the bak file to convert it to normal kdbx file.
The "save to" button still not display anything usefull to save locally.
When I choose save to "google drive", the page goes blank. nothing happen and I must close the app to retry something.
So I end up now with a bak file and I can not sync.
Im not an advanced user at all, and I may not quite understand most things, but now it feels so broken.
