Indeed, a note was included in a recent Stable update announcement thread under Known Issues and Solutions about the general replacement;
and in the Unstable update thread (July 2005);
- 2025-06-22 - linux-firmware-amdgpu-20250613.12fe085f may create an unbootable system for RDNA4 GPUs or graphical glitches with RDNA3 GPUs - the item provides workarounds and links for those affected.
However, at face value, this doesn’t seem related to the issue you describe; but it mightb be. With a little more detail, others should be able to help pinpoint the problem.
Please provide system information as described (below) and any other specifics that might assist those wishing to help.
Regards.
Welcome to the Manjaro community
As a new or infrequent forum user, please take some time to familiarise yourself with Forum requirements, and the many ways to use the forum to your benefit:
Update Announcements
The Update Announcements contain important information and a Known Issues and Solutions section that should generally be checked before posting a request for support.
System Information
While information from *-fetch type apps might be fine for someone wishing to buy your computer, for Support purposes it’s better to ask your system directly; 
Output of the inxi command with appropriate parameters will achieve this (naturally, formatted according to forum guidelines) and will generally be more useful for those wishing to help:
inxi --filter --verbosity=8
or the short form:
inxi -zv8
- inxi man pages (Arch Manual)
Be prepared to provide output from other commands whenever asked. It’s equally important to provide as much actionable information as possible in your first post, rather than simply indicating there is a problem.
