AppDesigner does not overwrite mlapp on Linux; works fine on Windows

Hi,
I'm trying to edit an app using App Designer on R2022b for Linux. The app has a fair number of components, but the number of lines of editable code is small (~100), since I exported all of the methods to separate m-files. I was able to do this and save the modified app using R2022a on Windows.
However, even with the much-shortened mlapp file, I cannot make changes and save it on Linux. It opens fine and I'm able to edit the code, but when I save, the interface does not show that the file is saved, and the modification time on the mlapp file does not change. Instead, a new, empty ".tmp" file gets created in the same directory. Every time I click save, a new one of these files gets created, and that's it. This screenshot shows what the app directory looks like after saving (app was last saved on Windows on the 25th):
Any ideas?

The problem appears to be due to a regression in the Linux kernel. More details are available at https://www.mathworks.com/matlabcentral/answers/1798895-invalid-cross-device-link-18-when-saving-a-file-on-arch-linux#answer_1095538
Some of the other posts in that Question give work-arounds for moving the temporary directory.

Thanks! I guess the workaround for now is to set the TMPDIR environment variable to somewhere on the same filesystem. Unfortunately I work with a lot of different filesystems, so I will probably run into this again, but at least I know how to fix it. Hope either the kernel or MATLAB gets patched in the next version.
