This is what I see whenever I try to download something in wayland torbrowser. I built torbrowser with wayland USE flag because xorg torbrowser doesn't run on sway.
Well, upstream doesn't support wayland. That's why the wayland useflag is masked https://github.com/MeisterP/torbrowser-overlay/blob/b15183a0d254711a3df8befb0e892d591f5bee4b/profiles/package.use.mask#L2
That means torbrowser doesn't work reliably on sway. Xorg torbrowser doesn't launch. Wayland torbrowser crashes before it shows me a file picker dialog.
Maybe something mentioned in https://github.com/NixOS/nixpkgs/issues/307095 will help you to fix your issue.
Setting widget.use-xdg-desktop-portal.file-picker to 1 (instead of default 2) seems to work around the issue for wayland torbrowser, but it also fails if it's executed in firejail because firejail profile is not updated, yet.
In torbrowser-140.4.0_p15000, I set widget.use-xdg-desktop-portal.file-picker back to the default value of 2 and tested downloading a pdf file from the internet.
Torbrowser doesn't crash anymore.
