Impress 7.0 crashes when it run a presentation

I’m on Debian 10. I had LibreOffice 6.3 installed from Backports.
It has been updated to LO 7.0 which is the current version in Backports.
Impress presentation has stopped working when I start (f5)
The program crashes when I try to make any presentation.
The output when executing from the terminal is:
$ loimpress
X-Error: BadMatch (invalid parameter attributes)
Major opcode: 62 (X_CopyArea)
Resource ID: 0x48038ab
Serial No: 81288 (81288)
These errors are reported asynchronously,
set environment variable SAL_SYNCHRONIZE to 1 to help debugging
Application Error
Any help, please?
