Problem in invoice creation form

Hello,
I just installed Akaunting and set it up but I have a display problem when I want to create an invoice. The form appears very quickly and immediately disappears. Tested on several browsers with the same problem.
Thank you in advance for your help

The developers will need more information to help solve your problem. Are you receiving any messages on your browser's console? You can view the console usually by pressing the F12 key and clicking on "Console".

Also, you can turn on the Akaunting's debugging by modifying your .env and changing the line APP_DEBUG=false to APP_DEBUG=true

You will want to post all of your messages so that we can help.
