<p>Hi, </p>
<p>"Invalid Data Source" normally means, that you dragged an
unsupported file-type. <span lang="en"><span><span>However, your
message is missing some important details, so it's difficult
to offer further advice:</span></span></span></p>
<p>Are you dragging files from filesystem (Windows-Explorer) to the
QGis-Window?</p>
<p>What kind of file are you dragging onto the QGis-Window?
(Unfortunately, this interesting part was obfuscated in your
screenshot...)</p>
<p>Does the problem occur in a blank new project?</p>
<p>What are the "5 more" problems reported in your screenshot?
(Note: You can see a list of all messages in the "Log Messages
Panel")</p>
<p>Regards</p>
<p>Ludwig</p>

<div dir="auto">Hello!
<div dir="auto">I'm using QGIS version 3.44.11.</div>
<div dir="auto">Here are the details of the problem: I was
working on a task in this program when it suddenly crashed.
The files I'm using are stored on my hard drive. So, I opened
the file I needed on another device to check it, and
everything works perfectly there—it opens and can be dragged
just as it should. The other device has the same version of
the program (3.44.11). But on my device, I get an error (see
the screenshot below). I’m sure the problem is with the
program itself, since this happened after everything else
stopped working: at one point, I lost the ability to open
polygons, which took me some time to figure out. Later, I was
able to do that, but the files still wouldn’t drag and drop. I
also know it’s not a disk issue, because I can drag and drop
other files from it, but the specific one I need won’t work.
The files are fine—it’s just the situation I described—and
everything works perfectly on another device. I’d appreciate
some help with this issue. Thanks in advance.</div>
