Thanks for the workaround, I changed the file in my docker volume and I can now access my files again. I am looking into upgrading to 64bit anyway so that will hopefully fix long term.
As a slight aside:
The official line on the System Requirements page (System requirements — Nextcloud latest Administration Manual latest documentation) is:
CPU Architecture and OS
A 64bit CPU and 64bit OS is required for Nextcloud to run well.
I am not sure about a fresh build but to me this defect means that nextcloud doesn’t run at all let alone well.
I think either the supported OS pages need updating to state that 64bit is required or this defect needs fixing.
What does anyone else think?
Update: I see there was another update on the defect ticket saying that it was an unintentional change to break 32bit versions. I’ve added a comment on there that the official System Requirements should be updated
