Error in pt-device-manager

This is disappointing:

Also when I fix your bug why does it remove my RTC on 68 - the UU in the I2CDetect.
It is getting worse.

I have updated to the latest versions of everything this morning and all I see is
10.002160] rtc-ds1307: probe of 1-0068 failed with error -121
in dmesg.
Why I tried to read the hwclock

pi@pi-top:~ $ sudo hwclock -r
hwclock: Cannot access the Hardware Clock via any known method.
hwclock: Use the --verbose option to see the details of our search for an access method.

How do I renable this on the pi-top ceed?
I works fine on ordinary raspberry pi OS.
