@SysUserR can you try with Dolibarr 20.0.2

[SysUserR]

In my daily working system I am using Doliwamp for an upgrade (Windows PC).
There the described failure message is comming from.
I now upgraded my backup system (Windows PC) from 19.02. to 20.0.2 with the Dolibarr ZIP-file manually.
The described failure message comes up in the same way, so the issue is existing on two systems (in my case).

I upgraded both systems with DoliWamp to V20.0.3.
On both systems I get the same warning like described above.
