Thunderbird Calendar - event reminder drop-down list blackened out

Since upgrading to Thunderbird version 91.0.2 ------ I'm unable to select an event reminder time. The drop-down box choices are a black font on a black background so pretty much unreadable.

Any suggestions ?

Try it in troubleshoot (safe) mode by holding Shift when launching TB. This will use the default theme, instead of the one you have that might be the cause.
