I recently installed the ARM64 version of Collabora Online for Nextcloud on my Raspberry Pi 4. However, whenever I attempt to open any given document with it, the loading screen stays at 0% then turns blank. A console log gives me the following messages (partially redacted for privacy):

Does this mean the Collabora Online container fails to start for some reason, or is it merely a matter of increasing the timeout somewhere? And if so, which files should I check?
