Unable to save image/file if there are 32 file name conflicts, "Sorry, an error occured" (Unable to save any file named image.png anymore)

### Steps to reproduce

Pick any image in a chat and save it 32 times, then try saving it again.

### Outcome

#### What did you expect?

I should be able to save an indefinite number of files with the same name

#### What happened instead?

After saving the same filename 32 times I am not able to save any file with the same name (even if it's a different file) because the file name already exists with suffixes going all the way up to (31).

This is huge problem because a lot of images have the same name such as image.png and I am not able to save any of those images anymore because I already have image.png, image (1).png, ..., image (31).png in my Download folder, and I guess the loop that tries different filenames gives up after 32 attempts.

Error from log:
