I have a similar problem here. After recent Ubuntu updates, I restarted my computer. The audio on the WF-1000XM4 started stuttering.
Reinstalled Bluez and PulseAudio. In the PulseAudio GUI there is a tab called Configuration. It constantly defaults codec LDAC (High Quality). When I reset it manually to LDAC (Mobile Quality) the sound is ok. After the next disconnect, the issue returns, and I solve it temporarily by changing the codec again. "Lock card to this profile" icon does not prevent it from resetting to LDAC (High Quality) again. The issue does not involve a Bluetooth mouse, the problem is encountered with and without connection to one. ASUSTeK COMPUTER INC.

It appears to work ok when having no other Bluetooth devices connected, but when connecting a bluetooth mouse the audio gets distorted and begins to stutter. The offending codec is ldac_hq. I did some investigating today and found out you can change the codec in pavucontrol. Selecting ldac_sq seems to work without any issue. I don't know what the problem with ldac_hq is, maybe bandwidth? Wasn't able to find any obvious problems in the logs, even when enabling debugging in bluez. While investigating this I noticed others having the same issue, and it was difficult to find a way to change the codec, so maybe ldac_hq shouldn't be chosen as default?
