After the latest update, the MacBook Pro M3 turns off when the charge is less than 20%. When connecting the charger, it turns on. No errors were found during the test. Please help with this problem.

The rule of thumb—if you are near the mains leave it plugged in, if you need the portability then run on the battery only—this is how you help optimize your battery charging and extend the working life of your battery by reducing the cycle count.
No SMC or NVRAM on the M1/M2/M3/M4 SoC
Therefore the best you can do if you have an issue— equivalent Shut down, close the lid 30 secs+ , reboot as normal.
If no resolve try SafeBoot to sort anomalies Start up your Mac in safe mode - Apple Support
Reboot as normal and test. Caches get rebuilt automatically.
