My site at https://diyshuttersandblinds.co.uk has developed a fault in WP Admin mode. I can't use the block editor any more with the AiF plugin enabled. The AiF block shows 'This block has encountered an error and cannot be previewed'. The console messages relate to several react.js errors. The block editor no longer works unless I disable AiF.

I have a staging site if you would like to login and take a look. It was working ok a while ago and not really changed anything for a few years so some sort of update has broken it I think.

Any advice please!
