In my for of CEF 90.4430.93 version (with many changes, admittedly) I am getting a crash in src/extensions/browser/api/file_system\file_system_api.cc.
It is a DCHECK(delegate) in FileSystemChooseEntryFunction::SetInitialPathAndShowPicker
I am not patching anything in Chrome, neither Chromium Embedded related to this.
It looks like a Save As... attempted on a PDF file (not sure if is really a file > saveas or a print to a PDF virtual printer invoking a save as from inside a PDF displayed file).
Callstack on Windows 10 build 19041.610 looks like this:

I am unable to reproduce the issue locally.
The DCHECK(delegate) obviously does not crash in release, so what is crashing is the next line 689 where delegate->GetDefaultDirectory() is called.
Locals shows pretty normal:
picker_type SELECT_SAVEAS_FILE (4)
suggested_name {path_=0x000032bc0070bae0 L"SEPA-formulier-automatisch-betalen-Wmo.pdf" } const base::FilePath &
file_type_info {extensions={ size=1 } extension_description_overrides={ size=1 } include_all_files=true ...} const ui::SelectFileDialog::FileTypeInfo &
(file_type_info.extensions[0] is "pdf")
delegate sadly, this is optimized away and not available
FileSystemChooseEntryFunction::ExtensionFunction::source_url is
source_url_ "chrome-extension://mhjfbmdgcfjbbpaeojofohoefgiehjai/index.html" GURL
so this leads me to think we are in the PDF viewer.
I'm not really sure what to ask except the obvious question: does anyone encountered this/reproduces this error?
