reinstalled Thunderbird 140.0.1esr (64-bit). When I attempt to Write a new email: gibberish shows p in the text body. Canot overwrite; have deleted previous version and reinstalled current one; followed trouble shooting steps in Safe mode without change. This doe not ocur in my Android devices. It appears in each of the two email accounts I have running in Thunderbird, 1) gmail, and 2) email account from my business website. I have been a Thunderbird user for 10+ years, and have not encountered this before. any assistance is appreciated! TYIA!
