Bug: Force Close when Rearranging Pin items in side bar

[Rockisaway]

Description

I just downloaded the application for files and it keeps force closing whenever I am trying to rearrange the pinned items in the sidebar. So far it won't let me actually save a new order.

Steps To Reproduce

1. Right click on the left hand sidebar under pinned
2. select the option to reorder pinned items
3. Rearrange any of the items
4. Either at force closes on its own or when I hit save it force closes the whole window.

Thanks for the report, the log doesn't show any errors, can you type Event Viewer into the Windows start menu search > Click Windows logs > Click Application > Screenshot the first error that have Files.exe shown on the first line > Send this on GitHub (Email attachments don't work)

I had this as well this evening on the 1st usage. Once reopened, the app seemed ok and didn't do it again on reordering them.

@Rockisaway Can you provide the asked information above

@Rockisaway Can you see if this is still an issue in the preview version https://files.community/download

If so, can you type Event Viewer into the Windows start menu search > Click Windows logs > Click Application > Screenshot the first error that have Files.exe shown on the first line > Send this on GitHub (Email attachments don't work)

Please screenshot the error. GitHub will format the text wrong otherwise. Can you also try the preview version

Unfortunately it only says that Windows force closed Files with no reason as far as I can see.

I found that even unpinning folder crashes as well.
And every time it crashes, a few top folders in my quickacess folder will disappear.
I remember this works perfectly fine in older versions.
