Hello, I played minecraft fine yesterday (and the past few years) on my Ubuntu 18 PC. Today, I start the launcher and it downloads an update. After the update, the launcher fails to open every time.

Launcher log says that there is a missing dependency, GLIBC29, but I have the latest libc6 installed for Ubuntu 18. I did apt update and upgrade without success. Is there any way I can go back to the old launcher that works? Thanks for any help, it sucks suddenly not being able to play the game I paid for

launcher_log.txt: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.29' not found (required by /home/collin/.minecraft/launcher/liblauncher.so)
